Thar's hardly a classic kung fu movie. It was a hollywood kung fu movie. I think "Way of the Dragon" is better, but I prefer "Who Am I" overall and "Gorgeous" for the fight scene, but old skool it's gotta be "Police Story".
I have seen police story a few days ago, man there are realy some great action sences (espescialy in the end) in that movie. Ok the story sucks but thats fine with me.
I also like some old jet li movies, jet li just kick ass.
And i saw "five masters" yesterday, also kinda cool
there are so many i dont remember all, but i like some of Bruce Lee(10 fingers death hand?)
-> Drunken Master with Jackie Chan
-> China Sword Man ( not that old but i like it )
-> Shaolin Kickboxer
and many more
