Here are two of my favorite foreign films that I think everyone should watch:

Battle Royale
http://www.imdb.com/title/tt0266308/

Japanese film where every year, a high school class is randomly chosen to spend three days on a remote isolated island. There they must fight and kill each other off until only one student is left, who is then let free to go back home. The Battle Royale act was passed in Japan after a non stop rise in teenage defiance towards adults and organized society.

Oldboy
http://www.imdb.com/title/tt0364569/

South Korean film in which a man is randomly kidnapped and placed in a room with nothing but a television and pad of paper. After 15 years of imprisonment, he is let go and is given 5 days to figure out who imprisoned him and why. This is part 2 of Chan-wook Park's loosely based revenge trilogy.

Oldboy is EXCELLENT. The ending is, well, it takes a lot to make me feel uncomfortable but this movie achieved it. One more of those movies which will make you feel uneasy is Man Botes Dog. This is ONLY for those with very very very thick skin. This is one of the most disturbing movies ever made:

Man bites dog ( http://www.imdb.com/title/tt0103905/ )

This movie is about a documentary crew following a serial killer/rapist. It is a french film. I watched it and the violence of it captivated me it was so over the top. I know people who have felt ill after watching it. So weigh up your tolerance and consider renting this.
