Where can I watch classic pelikula online for free, but without downloading?? ( I don't want anything to happen to my laptop)

You might want to try the Internet Archive at link

Also, Hulu at link might have some. Other places to look are link http://www.abc.com and link which mostly have TV shows but might have some classic pelikula as well. You might be able to find something at Xfinity (if they're still around) or Crackle. You'll have to look those last two up on a paghahanap engine, since I don't remember the URLs for those.

Anyhow, that otta get you started. :)

You can find many on YouTube (though I'm not sure about pelikula starring all those specific stars you listed). I watch great pelikula on it all the time! Just as great is the site or better VeeHD.com though I do not say much about it here as I don't want to cause it to be taken down. But I would say DO NOT go there if you don't know much about browser plugins. I pag-ibig to help people so just message me anytime if you want madami info. In the meantime here are some samples of great pelikula on YouTube (Btw, you can find other pelikula sa pamamagitan ng taking hints from the pamagat of the video and others in the "Suggestion" column):
Pigskin Parade (Judy Garland's first movie)

Thirty araw Princess (starring Cary Grant and Sylvia Sidney)

I could of course go on and on but at the moment I got another job to do so I'll just say if you want you may go to my channel WWIIDDSS and go to my "Motion Pictures" or "Movies to Watch" playlists to find other examples. I hope this helps. Have a pleasant day,

Just go to google paghahanap and type in "viooz" then you can paghahanap either the title, actor, or director of the movie you might wanna watch in the paghahanap bar. If you want a recommendation, I suggest you type "Thoroughly Modern Millie" in title. I pag-ibig it, and I think you will too, if you haven't watched it. :)
