Tough choice but I'd have to go with
300-I've always been a fan of that historic event
House of Flying Daggers-I'm not a big fan of love stories, but I really enjoyed this one
Spirited Away-I actually got to meet the director, Hayao Miyazaki
Tokyo Gore Police-If you don't mind subtitles and are looking for good WTF just happened B movie you might enjoy it
last but not least probably the movie that I recommend to every one, and enjoy seeing there reaction as I tell them about it
Dumplings-This one needs some explaining. It's a Chinese horror film so again if you don't mind subtitles check this shit out. You can see it the full movie which is titled Dumplings or you can see the shortened version of it in a movie called Three Extremes. All I will say is this, it's about an aging actress's obsession with recapturing her youth leads to an unnatural diet.
"SPOILERS!!!"
and for those of you wanting to know what she eats, which I'm not sure if this is much of a spoiler, I don't really think it is but I said it just in case. She willingly eat aborted baby fetuses. This movie is at the top of my list because A: I've never seen anything like that in any other movie, B: Here in the states it would offend sooo many people C: I have a fucked up sense of humor.
