Other mistake: When Ralph is leaving on his bike he passes the same rock twice.
Other mistake: In the party scene, the monster chews repeatedly on a blonde man in a white tuxedo while suspiciously humping a table. This happens while Slade locks the car. There's another shot of the partygoers running away scared, but that is recycled from the earlier bit when the alligator tail-whipped a security guard earlier; the guests that are running away are the exact same (look for instance at the woman with the brown dress and the black belt). You can even spot the security guard flying again in the air like a minute earlier. (01:16:25)
Other mistake: It's a funny line, sure, but when Jane is with her fiancé, he tells her that her mother and her lesbian partner "adopted a black baby" and "last week, she hocked her wedding ring to buy a crib." That's a little fast, considering the relationship happened just a little before the heist planning, a week. (01:04:20)
Other mistake: It is night-time when Dr. Tart (Conway) releases the 2nd dove out the window. Moments later we hear 2 gunshots and a plop sound of a dead bird. Which would be impossible as the shooter could not see a gray bird in the night sky.
Other mistake: When Voltan murders the nun who betrays the group, there are a number of errors in quick succession. First, he appears to stab her in the arm, judging from the position of his body to hers when he stabs her. Second, there is no trace of blood on the dagger when he holds it up a second later. Third, her body seems to have disappeared (or at least moved) when the camera changes to a wider shot a second later. (01:15:19)
Other mistake: If Terrible Tommy's the world champion then where's the title belt she should be wearing?
Other mistake: When they are running through the surf and up the beach in North Africa, there aren't any landing craft in the sea behind them. (00:10:22)
Other mistake: After Lord Buntaro's archery demonstration, Blackthorne comes over to the post which now bears the three arrows shot by the Japanese. In the paper wall behind him a hole can be seen, which is to be the spot through which the arrows have come. but the arrows and the hole do not make one straight line, which would have to be the case if the missiles were to really have arrived from there.
Other mistake: During the end of the movie, when Popeye sings the title song, if you look at the bottom right of the screen, you can see the runway type platform that he dances on until he goes off the end, and ends the movie.
Other mistake: When Justices car gets crushed as is almost triangular shaped, and driving down the road, it shows a shot of Justice cleaning off some dirt from the dashboard. If you look at the hood/bonnet where all the crease marks are from the crash, you can see quite a bit of rust where the paint has flaked off. Considering the damage is only supposed to have just happened, there should be clean metal not rust.
Other mistake: When Skip emerges from the box where he has been locked up for five days, he has no more than about one day's stubble on his unshaven face.
Other mistake: After rescuing the boy, Jamie gets the 1946 Ford truck stuck, having rounded vent window frames. But inside as she tries to move the truck we see "dogleg" vent frames from say a 1963 Chevy truck (more pointed, angled back).
Other mistake: When John is talking about the murder of the child Claire yells at him to stop but refers to him as George. George C Scott is the actor's real name. (00:57:35)
Suggested correction: This is a misconception. In the movie, Trish Van Devere did not accidentally call him George! Not true.
