If Bruce Lee did MMA

Essentially, he sort of did. He did learn Catch/Pro Wrestling from Gene LeBell just so he could work with American Stunt teams and because he realized the importance of grappling. Bruce also picked Wally Jays brain for some knowledge in Small Circle Jiu Jutsu. Bruce helped Gene LeBell to take movie fights to a whole other level. Before Bruce you MIGHT see some martial arts in film. After they began to take off into mainstream film. But JKD was integrating striking, weapons and grappling long before the UFC.
