For me it’s Rashomon. I’m not saying it’s the best foreign film I’ve seen but its meaning to me goes beyond the viewing. The first time I saw Rashomon I was left wanting more. I knew then that foreign film didn’t mean stuffy British drama, French skin flicks, or Hong Kong chop-sockey. There was a whole world out there and they’re making movies too. I just had to seek them out.
Let the right one in>twilight
Oldboy is awesome but the other 2 movies by park are great to,Lady vengeance and sympathy for mr vengeance, both are worth checking it for sure.
Audition

seven samurai(really all the kurasawa films)

That's a hard question because several come to mind for different reasons. I'm going to go for In the Mood for Love by Wong Kar Wai. It is also a quiet movie but so well acted and written it keeps you mesmerized and attentive that its quietness isn't a problem it is actually part of the movie. Also one of my favorite romantic/drama/period pieces.
Casshern-Because of the way Kazuaki Kiriya mixed a bunch of genres together to make one low budget masterpiece.I recommend it if your a fan of science fiction or Anime.
Night Watch-A wonderful Russian drama fantasy with elements of horror. Although I love the sequel better,this one still kicks ass.It has the main character that most of us can relate to and the action stunts we wish we could do.Also it has the best subtitles EVER!
A Bittersweet Life-A Korean film that is similar to Old Boy except better.
