Anna and Kristoff to sumali Elsa in Once Upon a Time 

is planning a big chill for Season 4, with the introduction of not just

TVLine has learned that casting is now underway for the aforementioned conflicted ice queen — who was glimpsed (and played by a stand-in) at the close of Season 3 — as well as her sister Anna and ice merchant Kristoff. Elsa will appear in approximately nine episodes, the others a bit less. (Hey, maybe Kristoff runs Henry’s favorite ice cream shoppe?)

And before you ask: As previously reported by TVLine, the show bosses laughed and offered a “No comment” on the prospect of a CGI Olaf showing up.

In Disney’s animated blockbuster, Elsa, Anna and Kristoff were voiced by Idina Menzel, Kristen Bell and Jonathan Groff. The ABC’ series’ character breakdowns are below — spoilers for the movie

, be warned! — so give ‘em a close read and hit the Comments with your dream casting suggestions.

ELSA | The Queen of Arendelle, this late-20s/early-30s beauty long struggled to control her “chilling” powers and even unleashed upon her town an eternal winter during her coronation. Ultimately, she realized that the key to controlling her powers is love — namely, her bond with sister Anna — and now she is aware of the threat she poses if she were to lose control of her magic again (in which instance Vancouver weather could rival Winnipeg’s!)

ANNA | Elsa’s slightly younger sister is a fun-loving, fearless optimist who often gets herself into situations where she is in over her head, yet is able to triumph due to her resourcefulness and can-do spirit. She values her relationship with her sister above all else.

hearty, salt-of-the-earth ice cutter spent most of his life alone (unless you count his reindeer). He has a sometimes-gruff demeanor that can hide his deep love for Anna and her sister Elsa. When we first meet Kristoff on

, he is adjusting to life at the castle — including sleeping indoors for the first time in his life.

Much as I love her, Megan Hilty is currently expecting her first child, so you can probably kiss that idea goodbye as she’ll be heavily pregnant by the time they wrap up Elsa’s storyline.

They can always shoot Megan from the neck up until she has the child. It lets Wardrobe get very creative and possibly an Emmy if they do it right.

Um… have you *seen* Snow White’s wig? LOL

Anna’s alive? More ‘sisters’ plot in the future I guess. I was kinda hoping Rumple did something to Anna, causing her to die and Elsa is out for blood.

But I’m crossing my fingers, I mean the writers are clearly good at writing twists.

Olaf and Sven can be merged into an animal character or kid. Just an idea.

I don’t think they can kill Anna. The writers all have a deep love for Frozen and killing off the main, most beloved character would not be their brightest move. Besides their children would kill them.

Anna would not have to be dead. She could be cursed into suspended animation or be trapped somewhere…?

Well, in the original book anna didn’t even know elsa (snow queen) and anna’s childhood friend is ‘dead’ (not really, just heartless — seeing the darkness of the world — and living with the snow queen in her castle where he’s dying slowly.)

Maybe they’re going to base the story off ‘the snow queen’?

Hmmmm, how about they be played by…Idina Menzel, Kristen Bell, and Jonathan Groff!

Bonnie surely is flattered that you think she is “late-20s/early 30s” :)

… How is Elsa “late-20s/early-30s”? She had just become of age and been coronated in the film. Wouldn’t that make her more likely to be, say, 21?

I don’t think they’re casting her as she was in the movie, but rather some years removed from the events of the movie. As if this was a live-action sequel to the animated movie.

And besides, she’s likely going to retain more of her “The Snow Queen” qualities than her Frozen qualities, while using the Frozen aesthetic (as the most recognizable designs of these characters), and characters. And Tangled may have still happened, but with the timeline advancement, a case with the black Rapunzel we’ve already seen without a captor like Mother Gothel, can still occur. Like how not every kidnapping or shooting is reported on the news, there are other stories of tower lockaways untold in FTL

I liked Rapunzel, but I really like Tangled and wish they had used that version of the characters and story instead.

… Does this mean the inevitable “look we’re gonna talk about Kristoff ad Anna’s children-” oh god. Tell me, Adam and Eddie, planning on getting some kiddie blood on your hands? So that Elsa has a reason for her rage?

Else didn’t seem evil to me in the movie. I can see her becoming evil if something had happened to Anna and she lost her tether. Maybe she died, Elsa lost her, um, cool, and Rumple had to imprison he to save the realm.

I like the show, but I’m skeptical about the Frozen move, but at least it will be for 9, eventually 11 episodes, like they did with season 3.

Provided they’re flexible with the “late 20s/early 30s” thing and willing to cast Elsa in the same age range as Regina and Zelena, I would love to see Sarah Michelle Gellar in the part. From her work on Buffy the Vampire Slayer and Ringer, there is absolutely no doubt in my mind that she would do justice to Elsa’s inner turmoil.

Now, the trick is the show shoots in Canada and Ms. Gellar might not be willing to leave her children for an extended period of time to appear on the show. Unless of course they are big Frozen fans and she can’t pass up this opportunity! Really hoping that the showrunners make an offer to her as I think she’d be a perfect fit.

I couldn’t agree more. That would be brilliant casting. I’d watch in a heartbeat

She would be a great choice but the fact is she is too famous for the role. Given that Frozen came out only a few months ago & that we all loved it sooo very much (isn’t Elsa the most adorable, albeit feisty, Disney queen ever?), it’s hard for fans to embrace a different portrayal of Elsa so soon. It’s like unveiling a new James Bond just 6 months after Daniel Craig made his debut in the role so awesomely in Casino Royale, but with the added twist that Casino Royale is the first Bond movie ever. Imagine that? Brain Freeze!!!

Best way forward: Cast somebody lesser know, like when they casted Lana Parilla & Ginnifer Goodwin as Evil Queen & Snow White respectively. They were both relative unknowns before OUAT compared to SMG now and it worked perfectly. Jennifer Morrison was the only well-known face playing a major character which was okay as her’ wasn’t a part of any Disney tale.

I feel like Ginnifer Goodwin was just as well known as Jennifer Morrison.Jennifer Morrison was known more for being on TV shows and Ginnifer Goodwin had been in a lot of well known movies like He’s Just Not That Into You and Something Borrowed

I get your point, but I feel Elsa’s introduction in the season finale sort of set the stage for a big-name casting coup.

As for the original cast, it was a nice blend of familiar and fresh faces IMHO. The only ones I wasn’t familiar with were Joshua Dallas and Jamie Dornan. Robert Carlyle was certainly no stranger to wide audiences. As an avid TV watcher, I had seen Lana Parrilla work her way from one show to another over the years and even knew Jared Gilmore from his days on Mad Men. IMHO, Ginnifer Goodwin was pretty well-known already from the five seasons she spent as one of three main females characters on the HBO series Big Love and appearing in movies such as Mona Lisa Smile and Walk the Line. At least as well-known as Jennifer Morrison, whose main claims to fame up to this point were, her series regular role on House, M.D., a recurring role on How I Met Your Mother and a very brief appearance as Kirk’s mother in J.J. Abrams’s first Star Trek movie.

Anyway, I guess what I’m trying to say is no matter how famous the performer, it’s their job to make us “buy” them in the role they’re playing. It’s not really worth losing sleep over, since we don’t really have a say in who they eventually cast, but it’s nice to dream and fun to play the guessing game. :)

Yes. If anything could get me on board for Frozen being brought into the OUaT universe so soon, it’d be SMG as Elsa.

The addition of Frozen characters feels a bit shark jumpy for me. OUAT is a cheesy guilty pleasure for me but Frozen? I will watch of course, but I’m not so sure how this will play out.

The real story of Frozen is hardly cheesy and will play well in that world. Most people forget that behind most Disney movies is a Grimm Fairytale.

But they’re not doing the Grimm fairytale, they’re almost certainly doing Frozen as most of the stories they’ve told have been closer to the Disney movies than their source material. At the end of the day, they’re only doing this as a cash grab because Frozen is as successful as it is which qualifies it as “jump the shark” worthy.

They’re really not. They were talking about how all the writers just love Frozen and really wanted to have fun with the characters while still doing them justice. Of course every showrunner cares about ratings, but that wasn’t the primary reason in their choice- it was creative potential

However coming off a season, where a lot of their audience was not satisfied with, bringing in a story line connected with a very loved Disney movie and story is a little convenient. Of course that’s just my opinion.

No one knows what they are doing because we haven’t seen it yet. I think people should give something a chance and if you don’t like it fine, but to complain about something you have no idea about is rather odd

Actually Frozen is based very loosely on a story by Hans Christian Anderson. Most fairy tales have different versions in different countries, and the Grimm brothers did not write the stores, just collected them from their part of the world. For instance Disney’s version of Cinderellla comes from the French version by Perrault. Of course i’ve never seen Frozen (and have no plans to) so I don’t really care who is cast.

In this case, it’s a Hans Christian Anderson fairy tale, not a Grimm one. :)

All of what you just said. Not only was I irritated with the return of Maid Marion, but when Else showed up at the end, I literally banged my head on the floor. I’ll give it a shot but if it starts to look to cartoonish, I’m out.

It’s totally jumping the shark. Hopefully they can pull it off, but if season 3 is any indication, they won’t. Good luck watching, cause I won’t be!

What about Anna Torv? I know she is mid 30′s but I think she would make a great Elsa.

She’s another great choice! I miss her. Hey – get Joshua Jackson to play Kristoff. :-)

Wouldn’t that result in a time-paradox violation leading to a multi-universal catastrophe?

Or we have entered another AltiUniverse. With these Faux Olivia and Faux Peter living in a magical land ruled by Queens. But Peter and Olivia never crossing over just the audience. (and Leonard nemoy plays Kristffos traveling companion)

OMG I love Joshua Jackson! Even though I never got into the whole fringed thing I have been a huge fan of his since he was about 13 (mighty ducks lol)

Come to think of it this is both an unexpected (being a big Fringe fan how come I didn’t think of this earlier?) but very applicable suggestion. Dingle with her hair (hey Anna Torv is already a natural blonde) a bit and you’ve got a mature Elsa!

OMG!! I was thinking the exact same woman for that part!! Adore Anna Torv, and her big eyes would make a great Elsa. (Just add Joshua as a love interest and I’m dead)

I know he’s busy with his own show but I would love to see Jonathan Groff on Once!!

I recommend Elizabeth Mitchell as Elsa Kristen Bell as Anna if they can’t get them my other recommend is Sarah Michelle Gellar as Allison Scagliotti as Anna Matt Lantar as Kristof or Aaron Ashmore

Luke was the first person I thought of too! Definitely on board with this idea

What about Psych’s Maggie Lawson as Elsa? That could possibly work.

Oh how about Alona Tal! Mainly because I want to see her on a TV show again.

I’ve been saying Alona since I saw the end of the finale. She fits the age range perfectly, she has the looks, and she’s super talented. And while I doubt Once will go the musical route, she can sing too, so that’s just a bonus “in case” bit of info.

mine too. Dianna would be perfect! Wish they would get her

Why? it does make a pretty good plot for the season. And who else would make a good villain? I’m you got Regina (once), Cora, Peter Pan, and Zelena the Wicked Witch of the West. Somebody’s gotta top those guys so why not Elsa?

Still not crazy about them cashing in on Frozen, but I guess if anyone was going to do it Once makes the most sense… Just annoying to me as a guy who read the Snow Queen story as a kid seeing it fast-tracked once a somewhat loose (though awesome of course) adaptation came out only about half a year prior. But pointless and silly ranting aside…

Ona Grauer available? I know she might be a bit older than one would like but I think she could make a good Elsa.

Maggie Grace or Brianna Brown for Elsa. Deborah Ann Woll or Jane Levy for Anna. And Lucas Till or Wyatt Nash for Kristoff. All great actors and I think they could each bring something interesting to the characters.

Ooooh Brianna Brown I didn’t even consider her before but she would be a great choice. I can definitely picture her as a slightly mean Elsa.

Brianna Brown will be on ABC next season, but probably not as Elsa on OUAT. She’s a series regular on The Whispers. Although that show is moving production from L.A. to Vancouver, it’s still highly unlikely she’d have the time to be on both.

How about Alison Mack as Elsa? She was great on smallville and can actually act.

Dianna Agron and Ashley Tisdale for Elsa and Anna, Jonathan Groff or Shawn Ashmore for Kristoff

Patrick J. Adams as Kristoff. He’s awesome on suits

Zachary Levi for Kristoff, I wanna see that sweet, goofy smile again on my TV !!!

My knees went weak at this suggestion so apparently I agree.

Yes!!!! Although Charming might feel threatened by somebody hotter than he is. :-P

That would be interesting having them in the same show since he took over Joshua Dallas’ character in Thor The Dark World because filming would have conflicted with OUAT filming. Good suggestion though, I like it :)

If anything could pull Emma Stone back to TV it might be this. If she retains her natural blonde hair, she could kill (metaphorically, please) as Elsa; if she was willing to go back to red, she’d be even better as Anna.

Ansel Elgort would definitely work as Kristoff.

What about Mandy Moore as Anna? She’s a good age and has been acting. I think she’d do the role justice.

So any guesses on which main character she is weirdly related to? I wonder if they are going to off her like they did Zelena. I would give the creators a standing ovation if they went that far just for the heck of it.

My vote is that Kristoff was one of the Merry Men.lol. and they have some kind of weird connection thru Robin instead of Regina or Rumple this time. But it’s probably some weird connection to Rumple, I mean he did have her in an urn in a “storage closet”.

Actually, I could see Kristen Bell playing Elsa quite effectively. Unfortunately, she’s busy and it might just confuse everybody anyway. (Plus, I don’t think she’d do it, meaning switch characters like that)

Molly Quinn could play Anna. I mean they’re hardly using her over on Castle anyway.

That would be an awesome choice. Plus she is a natural red-head (no crazy wigs!)

Thing is no matter how good the casting for Elsa is it will never be enough for us fans, mainly because she was so perfectly portrayed (voice, singing, appearance) in the animated film unlike many other OUAT characters. The Evil Queen or Prince Charming for example have had many different interpretations over the years (animated or otherwise) that there never is one particular portrayal that stands out, which is what made it easier to buy into their respective interpretations on OUAT. The fact that this move came so quickly after the first ever Frozen movie doesn’t help either. I would have rather preferred if Elsa was introduced in Season 5.

I am a fan and I see absolutely no problem with it. If they do it right and as I am enjoying their version of other Disney characters I am all in. I suggest before people start bashing it they actually watch it and than judge.

I was a little concerned when Frozen first started being mentioned because of the hype of the cartoon. But the more I think about it, I’m like, “they’ve not let me down yet.” I’ve got faith that this version of Elsa will make people go “Frozen Smozen. OUAT had the better version.”lol

I loved Kristoff in the movie :) so i hope he is similar here

Anyways look forward to how this all fit with Once and the characters. Also looking forward to the relationship of Emma/Hook and other couples there :)

Blake Lively or Clair Holt for Elsa, Alexis Bledel for Anna, AnnaLynn McCord (cause of her eyes) For either & Michael Ealy or Max Irons for Kristof.

Still wary about this story as a whole – hope it doesn’t take away from the core characters.

Yvonne Strahovski and Zachory Levi together again… (oh how I miss Chuck!).

I also liked Kristoff. I loved how he was there for Elsa, fell in love and he came back to her… reminds me of the dashing raspscalion Hook. I love him & Emma <3 .

I am liking the choices of which actresses, Alexis, Yvonne, Dianna etc

Yes, I know what you mean by Emma/Hook element – the whole he was there for ANNA (i got u meant Anna lol) and came back to her.

PLEASE don’t compare Hook and Emma to the perfection of Kristoff and ANNA. Kristoff – animated character no less – is ten times the man Hook is.

Excuse me? Hook is a far more developed character, than Kristoff ever was.

Don’t really gave a suggestion for who I’d pick except to say “not Elizabeth Mitchell”. Adam & Eddie seem to love her and since her last show was cancelled she ‘a available. She also falls outside the age range being mid to late 40′s . Fingers crossed that they pick someone other than her.

It be so cool if I could play Anna on the show. I love Frozen movie and Once upon a time show I really want to do acting someday.

What if they use young Anna for flashbacks and have her be old in the modern scenes? Angela Lansbury… Reprising her role of Mrs. Santa Claus, who I think they called Anna. Married to Kris(toff) Kringle.

It would be cool if only they hired regular people, too. I always wanted to try acting after high school drama, but I became a mom. So if it’s Disney, I am now an expert! My son is obsessed with Frozen and Brave!

Ex-’Bunheads’ Julia Goldani Telles would make a great Elsa, and Bailey Buntain a terrific Anna.

Oh I would absolutely love if Dianna Agron would return to TV in this role. She is the perfect person to portray the character-right age, looks, fanbase and of course has the talent to bring both the icy and vulnerable side of Elsa to the screen.

As a mom of 2 little girls who ADORE Frozen, I might have to give next season a go as the only show on Sundays I’ll have to watch is Revenge and OUAT might be good family viewing.

ELIZABETH MITCHELL FOR ELSA AND ANNA TORV FOR ANNA!!! P.S. Josh Holloway can play Kristoff!!!

Ijust wanted tocomment on your Winnipeg Reference .Itis not That Bad here!Well maybe this winter but not always..
