Free Science Fiction Movies
Sci Fi Channel has 14 classic science fiction movies that won’t cost you a cent. My guess is that these movies are in the public domain and can be found elsewhere, but they provide a convenient interface if you don’t mind watching flash movies embedded in a web page (full screen is buggy at this writing).
My Greasemonkey video downloader script doesn’t grab it, but there might be a way to download the movies if you look around. Public domain, remember?
