The net must be full of Public Domain films and old film that now is free, so where can I find a list of Public Domain films and old films that now are free? (Not independent movies).
Believe it or not, wikipedia has a pretty solid list of theatrical PD films. That's a pretty good start. Here's the link.

Wow, that was a goldmine, how cold I have missed that? Found a link to archive.org and a heap of great movies there. Thank you.
glad to have helped. Yeah, I happened upon that a few weeks ago.
Just to help everyone else out, here's the link to the archives.org collection of feature films, sorted by popularity (http://www.archive.org/search.php?query=collection%3Afeature_films&sort=-%2Fadditional%2Fitem%2Fdownloads). That's the best public domain movie source, by far, with the only downside being the crappy search engine.
