Noticed spud hadn't posted them at the main page. Both are from the great director Alejandro Amenábar whom later directed 'The Others'.
I highly recomend both of them as they really are great movies, if you can get over the fact that they're in spanish.
Tesis - Also know as 'Snuff'(imdb link)
has a whole bunch of different versions out there, all of whom are very well spread:
And a two cd version:
THIS IS SIMPLY AN AMAZINGLY GREAT MOVIE! SEE IT NOW! I have for about 10 times..
Subs can be found at http://dvd.box.sk/
Abre los ojos (imdb link)
also has a bunch of vesions out there, and I highly recomend this also, if not just for seeing Penélope Cruz topless in a long sexscene...
