Above post says the title for the charles bronson movie is hard times.
Charles bronson was a boxer in one of his early movies, he is more a street fighter as I recall but I don't know the name since I sold the dvd a while back. He generally beats folks up in most of his movies, but this one was pretty good when he had to fight the "ringer" the other guys brought in.
Clint eastwood in The gauntlet has a good fight scene when of has to jump a train and winds up meeting up with 3 bikers he pissed off previously.
The one with demi moore is G.I. Jane.
I sort of want to mention the highlander movies but I can't recall just how good those fight scenes were since it has been 5+ years since I saw any of those movies.
I think the movie is roadhouse where patrick swayze is a bouncer and his mentor is an older guy who winds up fighting this huge guy. That fight is pretty good. Then again, I have not seen that movie in a long while either.
