Bruce v Chuck Norris = Norris wins hands down he was the Karate Champion of the World when he filmed Way of the Dragon and his loss to Bruce in the Movie was obviously scripted.
Bruce v Jet Li = Tough because Jet is rediculously refined and fast but Bruce is Powerful... I would say its going to Jet because Bruce never competed professionally in fights and Jet was a World Champ 7 or 8 years in a row WUSHU...
Bruce v Tony Jaa = Bruce would smack his ass down if you don't know who Tony Jaa is watch Ong Bak: Tai Warrior
Bruce v Jackie Chan... I think Jackie could beat him by sure determination and the fact that he can take a real beating "Watch legend of Drunken Master" 1994 and thats all the proof you need...
but... if it was a timed fight i think Bruce would win...
The following are ppl that don't even compare to bruce:
Steven Segal has no chance what so ever even
JC... VanDamm
Jason Statham
Chow Yun Fat "Pff give me a break"
Jason Scott Lee ... even though he played Bruce... he has no chance.
Feel free to disagree with me lol
