pretty much similar to trout that's already been mentioned for me, Shichinin no Samurai, Old Boy, Battle Royale, Infernal Affairs etc.

Dare mo Shiranai is one of the better films I've seen, probably in my top 5 personally. Kikujiro no Natsu is also fun to watch, and has one of my all time favourite OST's because Joe Hisaishi is a badass. Also Kitano Takeshi.

Also, Jackie Chan. God damn I love me some Jackie Chan. In a full on Chan-spamfest at the moment. Police Story 1, Project A and Drunken Master hands down three of the best martial arts films ever made for mine. Although my personal favourite is Dragons Forever because smurf yes Sammo Hung and Yuen Biao. Even Yuen Wah got a spot.

I love some Thai films as well, and intend to try and watch more. Ong Bak is brilliant, imho the best martial arts action film ever made (though 2 and 3 are utter abortions, possibly the worst sequels ever), Tom Yum Goong is also excellent, and I love the thai film Chocolate too.

Also, Taxi. Taxi 2. smurf. Yes. I think the guy who plays the main character in those films is possibly the greatest Frenchman to ever live. Also probably the only acceptable French films full stop. Truffaut and French New Wave can smurf right off.
