Continuity mistake: Right before they rob the police car, a Boeing 747 (four engines) is seen in shots of the plane coming into land. When the plane is shown from behind, it is a Boeing 767, with only two engines and fewer main landing gears. (00:30:10)
Continuity mistake: There is a scene where everyone is dancing. It's towards the end but not at the very end. One of the employees of the record store takes his shirt off. Then the camera cuts back and you see the entire group of people dancing. If you look at him he has his shirt back on. Then a couple of shots later he has it back off again.
Continuity mistake: Tom and Huck have just swore they won't tell about the murder. Tom writes an oath, and Tom and Huck slit their fingers to sign it in blood. Tom, slits the index finger on his right hand. He signs the oath, however, with his index finger on his LEFT hand.
Continuity mistake: In a major fight scene two soldiers on opposite sides are jumping and spinning and tapping each other on the head with their swords.
Factual error: When Zach and Nomi are talking on stage after Nomi's disastrous experience at the boat convention, Zach places a call to Phil Newkirk. There are several problems with the call: the cell phone doesn't appear to be on (he raises the antenna at the beginning and end of the call, but he never presses an "on" or "off" button); Zach doesn't punch in enough numbers for the call to appear legitimate (too many numbers for speed dial, but too few for a local seven-digit phone number [also, since he was using a cell phone it's unlikely that he dialed a hotel extension number]); and the pauses between his words and Phil's response on the other end of the line are too short to be believable.
Continuity mistake: Hester's estrange husband mistakenly kills a man at the end, and you see him cut his hair and his scalp off, then later when people find his body (after his suicide) his hair and scalp are intact. Then later you see him with the hair and scalp in his hands again.
Continuity mistake: Moving out to Sera, Ben is packing his things in a motel. You can see a half full glass standing on a bed table on his left. In the next shot Ben is pouring alcohol to an EMPTY glass filling it in 1/3 approx. In the next scene glass is half full again and in the next one - FULL. Eventually he is drinking from a glass full of alcohol.
Continuity mistake: At Thanksgiving dinner when the turkey is spilled on her head. In one scene she is wet. The next scene she is dry again and then the next scene she is wet again.
Factual error: The suits worn by dangerous disease researchers would definitely never tear if the hose was pulled.
Continuity mistake: When Deebo is riding his bike to Craig's house the first time, one shot shows Deebo nearly on the driveway. Just then Smokey and Craig remove all their valuables. If this were true, Deebo should have seen these. But then in another shot, Deebo's bike is shown just coming onto the driveway. In that amount of time, Deebo should have been further up the driveway.
Other mistake: When Michelle Pfieffer hands out menus for the restaurant in the class, they all read them out loud in English. Then when she takes Raul there, he says he can't read it because it's in French.
Continuity mistake: When they are arguing in his bedroom, her scarf and coat are closed at one point, then open, then closed.
Factual error: When Lovell's daughter is complaining that the Beatles have broken up, she slams the album Let It Be into her rack. The scene takes place on the day of the initial explosion aboard Apollo 13, April 13 1970 - immediately prior to the Lovell family attending the screening of a television broadcast from the spacecraft. Let It Be was not released as an album until May 9th, 1970. In April Ringo was still recording drum tracks, not even possible for an advance copy to get out.
Continuity mistake: During the sales trip the two main characters stop at a gas station to get gas. during this stop Tommy bends the door back and after some struggle gets it to the normal door position. Before Richard gets back to the car however there is a shot of the door all dented up but in place. When Richard pulls the door off it falls to the ground and there isn't a single dent on it. (Also, is it me or does it seem a little ridiculous that someone that loves his car so much didn't notice the large dent down the edge of the door as he faced it while walking from the station to the car?)
Continuity mistake: When Gloria is confronting her "baby's daddy", her earrings keep disappearing and reappearing.
