Continuity mistake: When Adam Sandler reverses into the police car, he damages the Bentley he is driving at the back end. When the police chase him, the back end is not damaged at all. (00:06:35)
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.
Continuity mistake: Near the end of the film in the final game Ken Carter calls a time out. The clock stops on 36 seconds and after the time out it restarts again on 38 seconds.
Plot hole: At the beginning, it shows Santiago crossing the border into the U.S. But the U.S. border patrol is on the Mexican side.
Visible crew/equipment: When Jimmy Fallon and Drew Barrymore are taking their seats after the guy yells peanuts and crackerjacks, if you look carefully you can see some of the seats behind are actually filled with mannequins dressed with clothing. Some of them don't even have arms. (00:38:00 - 00:41:00)
Other mistake: In the championship game, the Yankees batter hits a foul ball when they score their winning runs.
Audio problem: In the scene where Phil starts to cry when he's kissing his wife, you can hear him say "I'm in way over my head" but his lips don't move at all. (00:34:20)
Continuity mistake: In the very first scene in the movie, where we see Steve listening to the motivational tape, he is wearing a red tie with polka dots. Then, when he is shown walking toward his boss' office and he falls, you can see that his red tie has changed to a gold tie. When he is in his superior's office you can see that it is back to red, and when he goes to find Stavi in the restroom the tie is gold again. (02:00:00)
Revealing mistake: In the scene where Stripes is looking in the water at his reflection, his body and the reflection don't quite match up. You can tell by his movements that his reflection is computer generated. (This is verified by the audio commentary.)
Continuity mistake: Just before Burt gets ready for his record-setting attempt, he wraps some asbestos cloth around his leg to protect it from the hot exhaust pipe. This does not allow him to fit his leg within the cowling of the bike, so he throws it off and puts his leg in without the protective covering. As he inserts his leg into the cowling, you can see that his pants leg is bunched up around his calf, not tucked into the top of his sock, as is Burt's usual procedure. However, a close up of the leg only a few moments later shows the pants leg tucked into the sock, and he could never have done that once he was fully seated in the cowling.
Continuity mistake: Just before the Breeders Cup the horse is upset and Kurt Russell puts his hands on either side of her face to see what she is "thinking". First his fingers are practically in her eyeball and when the shot changes his hand is back by her jaw. This happens to quickly to be a natural movement.
Other mistake: When the USA soccer world cup team is practicing in New York, on some field in Long Island, in several shots you can see the steeple for Union Avenue Christian Church, which is actually located in Saint Louis, Missouri.
Revealing mistake: In the scene when the coach's friend (priest) also played by Martin Lawrence is praying with the team. Every time it shows the back of the coach's head in line with the front of the priest's head it has noticeably less hair than Martin Lawrence and you can tell it is a stand in.
Continuity mistake: When Katelyn puts on her hockey skates, her leggings are not on. When Ronnie returns the skate it is white. Her skates suddenly appear as neutral and her leggings suddenly appear.
Factual error: The movie takes place during a single NFL season. In the beginning of the movie, when Brandon is still in Las Vegas, the paper he is using to pick games shows Seattle playing New Orleans. Later in the movie, still the regular season, Seattle and New Orleans are playing again. They would not play each other twice during the regular season.
Factual error: In an early scene, a character suggests that a man might be awarded an OBE honor if he wins the 1913 US Open. The OBE wasn't established until 1917.
Factual error: In the scene at the Miami hydroplane race, Mike McCormick spies a long haired boat pilot and naively asks one of the locals, "Is that Grizzly Adams?", to which he is answered facetiously, "Yeah, that's Dan Haggerty." The story takes place circa 1971, but actor Dan Haggerty didn't play Grizzly Adams 'til 1974.
Continuity mistake: In the scene at the end of the film when the Z-Boys finally get to skate in Sid's empty pool, the skateboard that is left on the steps changes position every other shot. When the guys first get into the pool, it is facing board-side out. In the next shot, it is facing wheel-side out. Then it alternates back and forth until the end of the scene.
