Boxing movies

I just watched the Fighter.  Christian Bale was great, the sisters were the least sexually appealing organisms I have ever seen, and it was based on a true story.  The last part means I now have to spend the next hour researching Mickey Ward and company, which is this annoying OCD thing I have.  It was a good movie, but is every single boxing movie the same?  I haven’t seen five white boxers since I was born, but every movie is about an Irish-American who overcomes the odds (except Rocky, who isn’t real).  Are there any movies about Hispanic or black fighters?  Does every white boxer not throw a punch until the eight round?  When is the Tommy Morrison movie coming out?  Does he fight HIV in the closing scene?
