Here's 119 SF movies, whose copyright have alledgedly expired, and are available for download in a variety of sizes (iPod and PDA!) I say alledgedly free of copyright because I haven't investigated whether they truly are or not, but looking at the titles I think I believe it....
Atom Age Vampire, Flash Gordon Conquers the Universe (episodes 1-12), Kong Island, Radar Men From the Moon (episodes 1-9), Santa Claus Conquers the Martians and so on...and on...
