I'm trying to find a movie from the 1980's that was played on HBO,Showtime,Or Cinamax
I believe it was call Super Fighter... can anyone help me out?

Do you have any more information about the movie, premise, actors, etc? This might be what your looking for Tong San ng foo (1978). The english title is Superfighters aka Five Superfighters.

The movie I'm looking for looked like a low budget US film
Its about a young boy who is a big fan of this cage fighting sport... and he shows his talents in the streets by beating the hell out of criminals... and the people who are head of the cage fighting bring him in to be one of there fighters...

Charles Bronson starred in a movie called Hard Times (1975) I have it. It's a good flick!

Also another good film while its fresh in my mind is Gladiator 1992 with Cuba Gooding Jr. also good flick. These are probably not it but check them out!
