u can find many on YouTube (though I'm not sure about films starring all those specific stars u listed). I watch great films on it all the time! Just as great is the site of 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 u don't know much about browser plugins. I love to help people so just message me anytime if u want meer info. In the meantime here are some samples of great films on YouTube (Btw, u can find other films door taking hints from the titel of the video and others in the "Suggestion" column):
Pigskin Parade (Judy Garland's first movie)

Thirty dag Princess (starring Cary Grant and Sylvia Sidney)
link I could of course go on and on but at the moment I got another job to do so I'll just say if u want u may go to my channel WWIIDDSS and go to my "Motion Pictures" of "Movies to Watch" playlists to find other examples. I hope this helps. Have a pleasant day,
Josh
