Revealing mistake: When they are all in the camper van Tiffany gives Chucky a biscuit then walks away from him, from the way she gave him the plate, they would have all fallen off. (01:07:35)
Revealing mistake: In the scene where Captain Love and Antonio Banderas (as Zorro) meet in the hallway of the hacienda, two guards rush down the hallway and drop their rifles and swords. Zorro asks them to bend over and then proceed to kick/nudge them out the window. If you watch carefully, you'll notice that the guard on the right (furthest from Zorro) reacts to the kick too early. (01:33:30)
Revealing mistake: There are several scenes Meg Ryan and Tom Hanks' computers do not have any telephone wires attached to them. They are in an era where they were using AOL dial up, as heard by the connection. They were not using wireless.
Revealing mistake: Just after they dump the tacks out of the window, the Russians' car flies up into the air in a really quite impressive car crash. Just before it flips over though, you can see the huge ramp put in front of it. (00:32:20)
Revealing mistake: When Dennis gets frustrated with the contraceptive foam and throws it aside, it is obvious that a machine is at the bottom of the screen to make all the foam squirt out, since it sprays from a different location than from where the cannister was thrown.

Revealing mistake: At the end of the movie, when François is waiting for Christine's call, he moves his hand just before the phone rings, as if somebody gave him a signal.
Revealing mistake: When Puffy the dog bites Ted and pulls him along, Ted digs his fingernails into the floor, they scrape along, making marks. If you look very closely you can see faint pre-made marks made in the floor, where he drags his nails along. (01:28:45)
