Continuity mistake: As paramedics inflate Jordan's assistant Stan Podolak following his lone bucket, the scoreboard shows the Monstars ahead 77-67 with 10 seconds remaining. Yet following his treatment and the surprise entrance of Bill Murray, the score has changed to 77-76 with no time having elapsed.
Visible crew/equipment: Just before the second fight with Clubber and just after the pre-fight brawl, when the camera switches to the shot of Rocky and Apollo you can see a director's chair at the top left of the screen with "Mr. T" written on it. (01:22:50)
Factual error: In one game the camera pans to Herb and behind him we can see a man wearing an Under Armor hat. Under Armor didn't come out until 1996.
Continuity mistake: Near the end of the movie, right before the semi-finals, they say that only eight men are left. When they introduce the men, they only call out six names.
Continuity mistake: Look at the dirt when Herbie backs away from the nose of the newer Beetle, between the races out in the desert. Although Herbie drove straight up to the newer Beetle, tire marks can be seen where the crew moved the car back and forth to get him lined up.
Continuity mistake: After Casey has turned down Harvard and is skating on the pond, she falls many times. When she falls for the fourth and final time, her hat falls off. In an overhead shot, the camera even shows it laying on the ground above her head. When she gets back up upon seeing Teddy with the zamboni, her hat has disappeared. (01:12:05)
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.
Revealing mistake: When Carl is caddying for the priest during the bad weather, the wind is so strong that it is almost blowing them over but the trees are not moving in the background.
Continuity mistake: When Ben Stiller goes to the girl's house in the white suit - she slams his head into the wall and a blood/makeup stain shows up...when the camera angle changes the stain is gone. (00:42:05)
Continuity mistake: On the double date when Juwanna goes to the bathroom and kicks off the shoes, one lands on each side of the toilet. The next scene shows them side by side.
Continuity mistake: When they get to the beach to surf the windows in the truck are left open, but after the shark attack Byron comes running back to call 911. The windows are now closed, so he has to throw the rock at the window and get the cell phone.
Plot hole: In the Cowboys' last possession of the final game, Spike makes a long run before being stopped on the goal line. The Cowboys' next play is a run up the middle. The Little Giants stop the run and the Cowboys lose possession, but since that was the first possession of a new set of downs, the Cowboys would have three more chances to score.
Continuity mistake: When the bobsled team is getting their act together in Calgary, there's a scene of them pushing off with an unpainted bobsled. In the shots of the feet of the guys pushing at the back of the sled, you can see that the lower back of the sled is painted black with green stripes, the colours that they paint the sled in a scene a few minutes later.
Visible crew/equipment: During the final fight, a steady cam operator with a white shirt and black straps around his body is seen during several wide angles. This is not a TV camera, it is a film crewmember. The Director even admits to it in the audio commentary on the DVD.
Continuity mistake: Ishmael (Randy Quaid) clearly has a tattoo of a four leaf clover on his chest when he is rescued from the strip club, well before they even make it to Reno, where he allegedly gets the tattoo. (01:08:20)
Visible crew/equipment: When Jake is in the bedroom with his wife (where he pours ice water on himself to calm down) you can see the top of some crew member's head in the foreground right below the camera lens.
Continuity mistake: During the scene with the guys dancing in the locker room, when the coach comes in, you see the same shot of Stefen taking off his jacket twice.
Factual error: One sweep through the town shows a Dodge Durango in a parking lot. The movie takes place in 1988; the first Dodge Durango was the 1998 model, ten years later. (00:34:15)
Other mistake: When Chozen is buying vegetables from the villagers, one of the weights from the scale is knocked onto the ground. Daniel picks it up and realises that its not a real weight and breaks it in half. If Chozen wanted to cheat the villagers when he weighed their vegetables, he would need weights that were heavier than normal, not lighter plastic ones. Lighter weights would mean that Chozen would need to add far more of the light weights to make any amount of vegetables balance out, therefore he would be paying more for the vegetables than they are worth.
Continuity mistake: When Joe gets injured and he insists the back-up quarterback goes in, he takes his wristband with all the plays on it off, so it can be given to the back-up. When the back-up quarterback is shown running on the field, he does not have it on, but when they show the back-up on the field, he does have the plays wristband on.
