Das Experiment - German movie about simulating a prison with average people. Very good and intense movie.
Audition - A movie by Takashi Miike.

Lammbock - German stoner movie.
The machinist - Don't know if it qualifies as foreign. It's in english and with Bale, but a great movie.
Killing Words - Very cool spanish film. If you want to get the most out of this film, you better don't know anything about it.
