In the Iron Man special features Robert Downey Jr. mentions he trains Wing Chun and he did some Jujitsu for his role which I thought was cool...little nod to Bruce Lee in a new Marvel flick.
Lee had WC for foundation in the blockbuster "Enter The Dragon" who's poster you see in "Saturday Night Fever" up on Travolta's wall with Pacino "Serpico" and that blond girl. Now Downey Jr. uses WC as foundation in the current popular block buster hit.
Brandon Lee had some for the feature "The Crow" Ip Man should be proud
