http://PublicDomainTorrents.info/ is a site full of old public domain movies. Almost every movie has been converted into 3 formats, Avi, MP4, and PSP compatible. The site itself is a tad outdated and can be slow and clunky to use. So I made a copy of every single one of the thousands of the torrents hosted on that site and put them all in one package.
This backup was made on 12/17/2016 I may make a biannual backup of this website if it's desired, please email me at email@example.com and I'll be sure to make you a copy.
The file itself despite housing thousands of torrents manages to only be <100mb so I'm sure it wouldn't be bothersome to seed
