Continuity mistake: At the beginning of the film, Mary and Roger's nanny Brenda refers to Mary as "Mrs. Anderson", but according to the credits, Mary and Roger's last name is Charleston.
Continuity mistake: As Hampton's family leaves town for Happy World Land, the car's odometer approaches 100,000 miles and, at this point, Wade grabs a camcorder with his right hand and starts videotaping the event. But in the next shot however he's steering the car with both hands - and still operating the camcorder somehow. (00:05:50)
Revealing mistake: When the attorney Ms. Lawlor is being 'hijacked' by the ghost (we only hear his voice) Grubeck in her car, it is very obvious that a person in a black ski mask and black clothes is driving the car.
Continuity mistake: At the end of the movie Gabe and Roy are sitting in the bleachers and Roy is wiping his forehead with a towel as Gabe starts talking to him. The camera zooms in and Roy now has his arms folded on top of the towel with his legs crossed.
Revealing mistake: When Bob Roberts falls off his motorbike, if you watch closely after he falls he gets up and faces to his right before the camera pans away. When the camera pans back a few seconds later, he's lying down again. It's obvious that the stuntman and Tim Robbins switched during this time, each hiding behind the parked car. (00:49:40)
Continuity mistake: As Lloyd leaves the stage asking what the show will be without him, Poppy's standing in the middle of the stage. But in the next shot she is leaning against the proscenium.
Continuity mistake: During the scene at Doug's house, Mathew's shoes suddenly vanish. He enters the house with them and then they are gone immediately afterward.
Continuity mistake: In the last scene, Tanya gets her arm cut on a piece of glass in the window by Charles, just before he turns to fight a cop. In the next shot the glass has disappeared from the window completely.
Continuity mistake: Watch the position of Joey's Mum when she is on the cart in the airport - she switches from being on the left side, then to the middle, finishing on the right.
Continuity mistake: In the scene where the brothers are sitting at the bar, Cesar lights up a cigarette and is holding it in his right hand. The shot cuts as he slaps Nestor on the shoulder with his right hand and the cigarette is magically in his left hand.
Other mistake: In the scene where Norman, his girlfriend and her family are seeing off her brother at the train station, you can see modern tractor trailers on the interstate highway in the background.
Plot hole: There's no way Dr. Lynn Waldheim's coat would have fitted Carter.
Factual error: Some characters are shown at Paddington Station and in the background the train shown at the platform is a 1920s Southern Railway green electric driving coach. Paddington at the time of the film was home to the Great Western Railway which never operated electric trains and never used green livery on carriages. Furthermore the carriage was issuing copious amounts of steam (accurate for the period and venue) but impossible from an electric train.
Other mistake: When Bobby sees Jimmy for the first time since being in prison, there's a Gameboy on the table. Jimmy walks to it and starts playing it, the problem here is that he never turns it on by the switch at the top, but you can hear the noises from the Gameboy when he's playing it.
Visible crew/equipment: During the breakfast scene, when Andrea stands up, a microphone is visible. (00:15:05)
Factual error: Rudy "Cheyenne" Cadena was not killed by his own gang as shown in the movie. In reality, he was killed by the Nuestra Familia, the rivals of the Mexican Mafia.
Continuity mistake: When Gwen is in the house discussing "what happened in Maui" with Becky (Davis is there also), her sweater sleeves are pushed up by her elbows. After she finishes the story she leaves the house. In the next shot, Davis thanks Gwen for making up the story (they are outside of the house). Her sweater sleeves are now down around her wrists.
Revealing mistake: During the standoff scene in the shipyard, Crazy Kung drops Tarzan (Tyson) from a magnet crane before reactivating the electromagnet, hoisting him up again. At the points where Tarzan starts dropping and where his fall is halted, you see a hole in the electromagnet and wires connected to the actor's back. (01:06:35)
Continuity mistake: Detective Keith Lui, after some fencing with the sugar cane, finds the only way out from the apartment is to throw himself out of the window. When he is leaping down, he is upright and looking straight ahead. When he lands in front of the group of deadbeats, he is horizontal and parallel to the road. (00:09:20)
