Hi Biomedic. Do you have access to public libraries? If you are very patient and very methodical, with a flash drive of sufficient size you could download the necessary files for the stand alone movies from the computers there. It would take several seperate trips, but it could be done.
If what you most want is just to see the films, a 128 gig flash drive should hold a portable version of winrar, all the rars to the MKV versions of all three films found here and have room enough for the extracted MKVs as well.
Once you have all the files to a particular film, you could use a portable version of winrar to unpack them onto that same thumb drive.
Watching them at home without a home computer, though, is a pretty tall order. I don’t think that’ll be possible unless you enlist the help of a friend with laptop you could borrow.
