Bruce Lee is an absolute legend, and I'll stop there (other wise I'll just keep crapping on).
Movie-wise, for me, it was definitely Once upon in China 2, that was movie that absolutely grabbed me (and a few of my mates, which lead to two chings, a honkie, a viet and a malaysian all singing the theme song aloud during physics classes in high school). The last fight between Jet Li and Yan Ji-Dan was just awesome.
And Tony Jaa is amzing, just saw Tung-Yum-Gung (is that how you spell it), amazing if the last bit where he fought with the elephant's bones (which was gay), the fighting scenes through out was amazing. The continuous scenes where he charges through the entire restaurant was incredibly shot. And I especially like the fact that he gets tired and slows down towards the top of the restaurant (as one would, smashing so many people along the way), this is how martial arts film should be shot.
I never liked Jackie Chan and his movies, and I never will.
