It makes for an interesting discussion. I argue the movie did not demonize Baer.
The Baer in the film was a libertine. True (I assume). Two of his opponents had died in the ring, or shortly thereafter. True. Do you think the historical Baer didn't cash in on how that enhanced his intimidation factor? Maybe did some trash talking? (By the way Craig Bierko's scary performance as Baer, the depiction of his physical presence, was great character acting and direction in my opinion).
Another film could be made that portrayed Baer in a better light, but I argue this one didn't cartoonize or demonize him beyond reasonable artistic license.
I hope this will be Bierko's breakout screen performance. In spite of being a hunk, he's been in only a few movies and TV shows - forgettable ones. He's also a terrific musical performer, nominated for the Tony for the 2000 revival of "The Music Man." Too bad the days of the Hollywood musical are over - he could be the new Howard Keel!
He didn't, his son became an actor whom you might remember from the Beverly Hillbillies.
That said, he grieved and paid for the school and looked after the kids of one of those boxers.
He didn't talk trash about, he didn't even like hearing about it.
From everything I have read, he was actually a very nice guy who got along with Braddock.
He made his big name by fighting a german fighter while wearing the star of david on his trunks and winning, he was a borderline hero for many.
