Deliberate "mistake": To make Jim Braddock look more heroic, Max Baer is portrayed as being very mean and hateful. In fact, the real Max Baer was an extremely pleasant man who was devastated when Frankie Campbell died after fighting him. Many boxing historians and sportswriters have complained about this inaccurate depiction of Baer.

Continuity: When Mae is at the sink washing dishes and, behind her, Braddock is teaching his kids how to box, Mae turns around and emotionally yells, "No boxing in the house!", the strap on the apron she is wearing is twisted. They cut away and in the next shot the strap is no longer twisted.

Continuity: When Braddock runs into Baer when he is taking his wife out to dinner, Baer insults Mae. She throws a drink in his face. He uses a napkin to wipe his face off. The shot goes to Mae, and then back to Baer, where his face is suddenly dripping again.

Other: During the Baer and Braddock fight, when the camera angle is from far away, you can see that Braddock is not actually connecting with his punches on Baer. Yet Baer still reacts like he's been hit. This also true with Baer hitting Braddock when the camera is showing the fight from far away in the stands.

Visible crew/equipment: If you look very closely when Braddock makes his son Jay return the salami to the Butchers, you can see the camera in the window of the butcher shop. It is more evident when they walk out of the store.

Factual error: In the scene prior to the Braddock/Baer fight, when Jim's wife Mae comes into the locker room and gives him the heartfelt spiel about being behind him in this fight after all, she leaves the room and as she leaves Jim, Russell Crowe, is standing there in a white "wife beater" tank top. It is a new one with a screened on tag by either Fruit of the Loom or Hanes. Screened-on tag tees didn't come about until the last few years.

Continuity: In the scene where Gould comes to tell Braddock that he got him a fight with Corn Griffin, they are standing in the open behind all of the apartments. In the background you can see an African American boy carrying a bucket of something through an alley. The camera angle changes and you see the boy start to walk up the alley again. It's the same shot, and it's right near the part where Gould tells Braddock that he will get $250 for the fight.

Continuity: When Braddock and Gould take their wives out to dinner, Max Baer sends them a bottle of champagne. When the waiter brings it over, everyone, including Braddock can see that the bottle is already open, yet he continues to tell the waiter not to open the bottle, that they will instead take it home with them.

Continuity: During the Lasky/Braddock fight, Braddock gets a cut on the right side of his face right by his eye. It lines up almost perfectly horizontal with the middle of his right eye. The next time we see him after the fight, when he is returning the relief money, the cut has moved up higher on his right side of his face.

Continuity: When Braddock is fighting Art Lasky, his face gets punched so hard that his mouth piece goes flying out of his mouth and hits the ground. There are drops of spit from the mouth piece on the ground that surround the mouth piece. However, about 10 seconds later when Braddock picks up the mouth piece, the drops of spit on the ground are gone. There is no way the spit would have dried that fast, no matter how hot the floor would have been with the lights on it.

Continuity: When Joe and Braddock are in the locker room, after he has just fought Corn Griffith, Joe is all excited and he starts opening locker doors to find his jacket. He finds his jacket and closes the locker door, but when the shot changes the locker door is now open again.

Continuity: The first time we see the relief office, it says, "Emergency Relief Aid." The next time we see the wall (when Braddock returns the money), it says, "Make sure that you have all of your forms filled out completely."

Other: During the opening scene of the movie with one of Braddock's boxing matches, he wins midway through the 2nd round. Yet, the clock on the wall behind the ring is straight-up, indicating that the clock had not even been started.

Revealing: In one of Braddock's early fights in the film, as his mouthpiece is being removed, his "missing tooth" was not blacked out.

Factual error: When Max Baer is told, in his hotel room, that he has to fight Braddock if you look closely you can tell that he is wearing contact lenses. They were not invented at the time.
