Im sorry I can't add pictures because I'm typing this from my iPod but I'll add the lookalikes names and you can look them up :)
* means that they look nearly EXACTLY like their lookalikes
Javier Bardem looks EXACTLY like Jeffrey Dean morgan (John Winchester)* Also Robert Downey Jn.
Jared Padalecki(Sam Winchester) apparently looks like Nick Wechsler (im sorry ealier on I wrote he looked like Neil Wechsler sa pamamagitan ng accident lol, if u want to end up in hysterics paghahanap neil wechsler up lol)
Jensen Ackles (Dean Winchester)-link and Emilio Eztevez (only a teeny bit though)
What an incredible end to Season 2! Jensen and Jared this taon were just mindblowing! The scene with Dean screaming Sam's name still haunts me, it makes me shake and tears through my puso every.single.time. AMAZING!
