Revealing mistake: When Jim is rescued from the snow (thrown over Reggie's shoulder), he moves his leg, although he is supposed to be unconscious.
Continuity mistake: When "Telly" and "Casper" leaves Telly's apartment, his shirt is white. In the next shot when it shows them walking to the park, his shirt is gray. (00:35:25 - 00:36:45)
Suggested correction: He changes his shirt at his house. You must have missed it.
Continuity mistake: Peter's hair position changes when he says the famous line, "Did you get butt-fuc**d in prison?" and after John replies "It only hurts the first time".
Factual error: Throughout the film they show exterior shots of Alcatraz. If you pay attention you can clearly see that the Warden's house is destroyed and all that remains is a shell. Also there is only 1 guard tower. Alcatraz had many guard towers but they were destroyed in the seventies by fire. The movie takes place in the late thirties.
Revealing mistake: Near the end of the film Willy jumps on a barrier in the water, causing it to break. During that scene its clear that the orca has been pasted into the background as the outline is too sharp.
Continuity mistake: When JC is in the car with his friends, he says Chloe has no money and between shots his collar jumps from under to over the seat belt.
Continuity mistake: Glen Holland owns a Chevy Corvair throughout the film. The car at the beginning of the film is a 1961 model 500 (the base model with bench seats), but at the end of the film it is a 1964 Monza (the top of the line model, with bucket seats).
Continuity mistake: When John leaves the table to get a refill on water, over half his burger is left. When he comes around the corner to see that Thad is gone, both the burgers are too.
Continuity mistake: In the scene where the two police cars are chasing the truck, the two police cars crash into each other and explode - as soon as this happens the truck mysteriously disappears.
Continuity mistake: When Deja and Malik are at the track talking and stretching, Deja is lying down in one shot then sitting up in the very next.
Factual error: In the movie, it is depicted that Verlaine shoots Rimbaud in the palm; in reality Verlaine shot Rimbaud in the wrist.
Factual error: In the opening scene with Doug Masters flying in Russian airspace, he is to be escorted back to American airspace by MiG-23s. But in fact the two planes that show up are F-4 Phantoms. When the "MiG" fires a missile, you see a completely different plane. Best I can tell, that is not a MiG either.
Factual error: The movie is set in 1948. When Easy first visits Albright about the job, Albright throws some $20 bills down in front of him. The top bill bears the signature of Treasury Secretary Nicholas F. Brady, which appeared on paper currency from 1988 to 1993.
Continuity mistake: When Dawn is getting food for Steve, she is shown pulling out a wooden tray, but in a quick shot change, the tray is shown on the table with a plate of food already on it.
Revealing mistake: At the cemetery, a reporter nudges a headstone and it moves, revealing it is fake.
Audio problem: On the video version, in the barbecue scene, the band starts playing the slow song. The camera is on Eddie and his daughter and they are dancing. If you look closely, the male singer in the background is shown standing on stage and just holding his guitar and not singing, even though the vocals can be heard. In a later shot, he is actually singing. Still later in the scene, he is shown just standing on stage and not singing.
Factual error: At a very early point in the film, the King says something along the lines of "....and these are your playmates". In the background is a horde of 17th century ladies boating on the Achille Duchenne water parterre at Blenheim Palace. The palace wasn't built until the late 18th century, and the parterre was not designed until 1925.
Continuity mistake: When Darius, Sterling and Jeffrey are talking in the anteroom at the memorial, the door leading out is shown open, then closed, then open again in three successive shots, but nobody is seen closing or opening it.
Continuity mistake: When Tommy is buying the right to perform the Parker brothers' material, Tommy asks to see the material that he's just bought. He stands up and turns the chair round so that it's facing away from the table. The shot then changes, and he turns the chair round so that it's facing away from the table again.
