I recently came across this site that provides rare international films that you can watch for free online. The World Cinema Foundation is a non-profit organization that is "dedicated to preserving and restoring neglected films from around the world – in particular, those countries lacking the financial and technical ability to do so." The foundation was established by Martin Scorsese.
