Yep. Wasn't James Toney playing Joe Frazier aswell? EDIT: Just checked and he was. Also, Alfred Cole - who fought guys like Corrie Sanders - played Ernie Terrell, and George Foreman was played by Charles Shufford - who fought guys like Wlad Klitschko and Sam Peter.
ILennox was in a movie with Vinnie Jones. He played a mad rasta who ran an illegal radio station. Tyson in Black & White and Croc Dundee 3 Scott Welch was in Snatch

Jack Dempsey was in loads of films through the 20's to the 50's such as "The Prizefighter And The Lady". Primo Carnera was in tons of movies during the same era too. Ken Norton was in "Mandingo" and a few others. Marvin Hagler was in "Indio". Lucia Rijker in "Million Dollar Baby" Sugar Ray Robinson acted in loads and loads of tv shows, not sure if he was actually in any movies though. There's a film that I think is called "Devil's Advocate" (?) starring Al Pacino and Keanu Reeves and there's a scene where they are at a boxing match, which just so happens to be Roy Jones Jr vs Bryant Brannon if memory serves me correctly.
Steve Collins plays a bouncer in Lock Stock and Two Smoking Barrels. Not a boxer, but Lou Dibella plays himself in Rocky Balboa
