Continuity mistake: When Arnold comes home after work, he always parks next to Kay's car in the driveway. As he does on the night Kay tells him they are going to the therapist's office. He is undecided about the trip and doesn't act to join her until after she leaves. Yet, when the taxi arrives to pick up Kay, there are no cars in the driveway.
Factual error: When Alma and Whit drive along the coast, the road has recessed center line reflectors. These hadn't been invented yet in 1959 when the movie takes place.
Continuity mistake: In the scene where Joaquin Phoenix's character is walking between a heavily wood-paneled wall and a window and banging on them: The first time he bangs on the paneling, one of the panels appears to split and swivel up showing white underneath. The camera briefly changes angles. When the camera returns to Joaquin Phoenix, the split panel is fixed.
Continuity mistake: Eden's hand and arm positions change between shots during the final scene in the movie, when she is kissing Adam.
Continuity mistake: In the very beginning, the truck that hits the vehicle does so from straight behind. However, when they pan out, someone the truck is perpendicular to the crashed car. The snow tracks don't show the car that was hit swerving, and there aren't any tracks to show that the truck reversed either.
Factual error: In one scene Drew Barrymore stands in from of a political world map, showing the political borders as of today. You can see the successor countries of the Soviet Union in that map. But the plot plays back in 1988, with the Soviet Union still alive.
Other mistake: When Christine is shot near the end of the film, there's no blood on her dress or the Phantom's hands.
Factual error: Kuklinski is looking at a newspaper which is dated January 3rd 1983, and the text reads that Roy DeMeo was found dead the previous day. In actuality, Roy DeMeo died on January 10th 1983. (01:22:55)
Visible crew/equipment: At the end of the movie when Sparkle is on stage singing in her red dress, a camera shot pans upward toward the ceiling on the stage. There is a cameraman backstage walking on a rafter or something, trying to run so as to not get caught on film, but fails.
Plot hole: In this Australian time-travel fantasy, a college student discovers a one-way time portal that allows him to travel one day into the past each time he uses it. While he at first attempts to rescue his girlfriend from a traffic accident that occurred a day earlier, he eventually travels back 50 years (one day at a time) to save his young grandfather. However, in order to go back 50 years (one day at a time), he'd have to repeatedly climb through the portal over 18,000 times. Apparently, it's not an issue, because the movie just glosses right over it in less than a minute.
Factual error: The Life One spacecraft is hit by a micrometeoroid. Sparks are to fly, among other effects. The sparks are bifurcated, meaning they were produced by using a grinder, not by a micrometeoroid collision.
Other mistake: After the medical student leaves the unconscious co-pilot to one of the other passengers to watch while he goes to the bathroom, she notices his hands grow cold after a bit. It is only then they realise he has stopped breathing, and then get a defibrillator out and are successfully able to use it to revive him with CPR as well. However if he has stopped breathing for long enough that his hands have started to get cold, he would already be way too far gone to be able to be revived.
Factual error: The movie changes between a basketball season and a playoff basketball game then to a baseball game being played in what looks like early summer...back to a team getting ready for the basketball playoffs. The two seasons don't overlap.
Continuity mistake: In the scene near the end of the movie where Ellen Miller asks Robert Miller to lift up his shirt, and then slaps him in the stomach with a newspaper, we see that his right shoulder suspender is properly positioned, however in the next shot from behind him his suspender over his right shoulder appears to be twisted 180 degrees. As he turns to walk into the inner bedroom the suspender is once again back to a proper fit.
Continuity mistake: The German and British airmen are looking at the Northern lights. From the rear the men are apart, but the front shots of them show them much closer to each other.
Continuity mistake: While he is copulating with Laurence, François Monge receives a phone call from his boss about the murder case in Bobigny. To shush his vocal partner, he gives her a slap on the shoulder, but he does it with the right hand in the view from behind, and the left hand in the full frontal. (00:08:55)
Revealing mistake: In the opening scene, Johnny and Hickey sit in the front seat of a car. Views out the side windows blur, there is a gray background behind Johnny instead of the rear window, and when Hickey holds the cross toward the windshield, the "outside" is all grayish-white. At one point, there is light on Johnny's right forehead, cutting diagonally downward (too linear to be the sun), and another time, there is light behind Hickey on his headrest. (00:00:31 - 00:03:30)
Other mistake: During the end credits, there's a misspelling. An 's' is missing from 'First Assitant Camera'. (01:33:05)
Continuity mistake: George's son is disappointed because his dad missed the ball game and tells him that he should have been there. Meanwhile Denise Richards approaches the cooking pot with her spoon in her right hand and the plate in her left. Close-up on her telling Howie that dad was busy, and spoon and plate switched hands. (00:18:45)
Continuity mistake: When Eddie Murphy's assistant makes assumptions about why Jack isn't speaking, he throws his notepad down and has empty hands as Jack pushes him out of the office. When the angle changes, he has a notepad in his right hand.
