Léon / The Professional Well, it's half-foreign. Plus it has NAT... when she's 12.
Zatoichi was a good samurai film. It has Takeshi Kitano, thus it has to be good. It even got a cinema release here.
More Obscure:
Battle Royale. Lord of the Flies + The Running Man. Really good.
Kamikaze Taxi: Starts out a bit strange, but towards the second half it turns into a reverse Collateral of sorts. Sublime.
Pacte de Loups / Brotherhood of the Wolf Sleepy Hollow + Period drama + Kung-fu movie + naked Monica Bellucci. Sounds good, right? Not an especially good movie, it really shouldn't work, but somehow it does. Has its moments. Superficially entertaining if you remember to check in your brain.
Infernal Affairs Hong Kong cop movie. Gangster pretends to be a cop, Undercover Cop pretends to be a gangster. Cue gunbattle like in Heat.
Le Bossu . The 1997 version. Not strictly an action film either. But it has its moments when it gets very swash and very buckle. Plot is a bit contrived.
I'll try to remember some others. There's also a Korean Band of Brothers type miniseries that's supposedly quite good. I would also like to see
this film eventually.
If it breaks, you get to keep both pieces.
