I actually just finished watching "Don King: Only in America". Ving Rhames plays Don King, I liked it a lot. It goes from Don King's early life as a hustler and convicted murderer to Ali to Holmes to Tyson.
I also like the new Tyson documentary and When We Were Kings for the documentaries.
out of the ones ive seen, raging bull(classic de niro, black and white with joe pesci) ...million dollar baby(clint eastwood classic)...girl fight(michelle rodriguez in bk)
