Continuity mistake: When Wayne and Garth are on their way to the Alice Cooper concert they show the car from behind you can clearly see that Garth is driving and Wayne is in the passenger seat but when they cut back to the car from inside Wayne is driving and Garth is in the passenger seat. (00:56:50)
Factual error: The baby is expanded to approximately fifty times his height, width and girth but it's explicitly stated that he retains his orginal mass. This means he will have the same volume as one hundred and twenty five thousand babies of his original size, but will weigh the same as before he was enlarged! That child is going to weigh much less than the volume of air he displaces. He's going to float away.
Continuity mistake: At the beginning, there is a scene where Ben spills a carton of milk. He picks it up right away, but a split second later the scene changes, the milk is still lying down, and he puts it upright again. (00:06:25)
Continuity mistake: During the trial at the end, Jessup struggles with the MPs to get to Danny Kaffee. After the struggle, his tie is all out of place. In the following close-up shots, it's re-aligned, before becoming completely askew as Jessup goes to retrieve his hat.
Factual error: In the scene where Bobby and Mike go into the comic book store, you can clearly see a Transformers comic on the shelf. But the movie is set in the late 1960's/early 1970's....and Transformers did not come out until the 1980's.
Continuity mistake: When Lionel's mum gets bitten at the zoo, the colour of her sleeve material changes from black/dark blue to light blue. (00:17:45)
Factual error: The glass shattering and falling in the greenhouse would have been unlikely to kill Marlene, let alone even cause that much damage to her, as the glass would have very little to no time to gain more force, falling at that low of a height. And if Marlene were to be killed, she would have probably bled out over time, as opposed to almost instantly dying as the film implies.
Revealing mistake: Towards the end of the movie where Veronica Roberts hands are tied behind her back, she goes over to the mulching machine to cut the rope free. But as she hits the blades they bend and move like rubber.
Other mistake: When Fergus finds Jude in his apartment (the scene in which she has coloured her hair red), Jude unholsters her 38 cal. and one can distinctly hear her cock the hammer. At the end of the scene, she places the gun in her purse with the hammer uncocked.
Visible crew/equipment: In the scene where Scott and Fran are dancing on the roof and the camera is about to pan downwards towards the lower level, to the left of the clothes-line, someone's head is visible moving. It is a crew member sitting against the other side of the wall.
Continuity mistake: Near the end of the movie, when Ed Leland is about to enter the Customs Office, the insignia on his hat is intact, but when he enters it has disappeared.
Continuity mistake: When Mr. McGuire is shot, he falls down, and Shannon's spoons spill out all over the ground. In an overhead shot, all the spoons are snatched up by bystanders, but then it cuts to a ground-level shot, and they're back on the ground, getting snatched up again.
Factual error: The Nina, Pinta, and Santa Maria are shown starting back for Spain at the end of the first voyage. In fact, the Santa Maria had wrecked by this time; the return voyage would be made only by the Nina and the Pinta.
Continuity mistake: Betty Lou is in the grocery store at the checkout. The cashier rings through her groceries which consists of a roast, veggies, flowers, dog food and a bunch of other things (she was shopping for her anniversary dinner), but she only leaves the store with the flowers.
Factual error: Throughout the film, the drainpipes on the buildings are almost all plastic - the film is set in the Victorian era.
Continuity mistake: When Allie takes a photo of the "perfect roomate", the roomate's pose in the photo doesn't match her pose and position at the time taken.
Continuity mistake: During a conversation a clock can be clearly seen in the backround and the time is 11:50, the scene cuts to a closeup of Nick Nolte speaking, then back to the wider shot and it's suddenly become 11:55 in a matter of seconds. But it doesn't stop there, it again cuts away for a few seconds and when it comes back to a a shot of the clock it now reads 11:40.
Continuity mistake: Near the beginning, Jake drives a motorcycle out of the warehouse shoot-out and spins out as police cars converge on him. He has blood coming out of the right corner of his mouth, the shot changes, cuts back to him and the blood is on the left, then right again in the subsequent shot.
Continuity mistake: During one scene, Mel Gibson is talking to the young boy through the treehouse door and holding the boy's jacket. The next scene, there is no jacket and then it magically reappears. (00:35:30)
Continuity mistake: The beginning scene involves two kids in the finals of the school championships. Why are there only adults watching? In a children's tournament all the other kids would most definitely be watching this game.
