Continuity mistake: There is a scene where dozens of police cars pull up the hospital's "driveway" to surround the building. In real life they could not be coming from that direction, the "driveway" is a park road that ends at a scenic overlook with no connecting streets.
Visible crew/equipment: After Jack jumps out of the plane he comes close to another Flying Elvis, who is being suspended from a visible cable.
Continuity mistake: At the beginning of the film, Mary and Roger's nanny Brenda refers to Mary as "Mrs. Anderson", but according to the credits, Mary and Roger's last name is Charleston.
Continuity mistake: As Hampton's family leaves town for Happy World Land, the car's odometer approaches 100,000 miles and, at this point, Wade grabs a camcorder with his right hand and starts videotaping the event. But in the next shot however he's steering the car with both hands - and still operating the camcorder somehow. (00:05:50)
Revealing mistake: When Bob Roberts falls off his motorbike, if you watch closely after he falls he gets up and faces to his right before the camera pans away. When the camera pans back a few seconds later, he's lying down again. It's obvious that the stuntman and Tim Robbins switched during this time, each hiding behind the parked car. (00:49:40)
Continuity mistake: As Lloyd leaves the stage asking what the show will be without him, Poppy's standing in the middle of the stage. But in the next shot she is leaning against the proscenium.
Continuity mistake: Watch the position of Joey's Mum when she is on the cart in the airport - she switches from being on the left side, then to the middle, finishing on the right.
Continuity mistake: When Gwen is in the house discussing "what happened in Maui" with Becky (Davis is there also), her sweater sleeves are pushed up by her elbows. After she finishes the story she leaves the house. In the next shot, Davis thanks Gwen for making up the story (they are outside of the house). Her sweater sleeves are now down around her wrists.
Other mistake: When the police drop their weapons to chase after the screaming woman who just took the concentrated love potion, you can see the machine guns have no magazine clips in them.
Continuity mistake: Mr. Maurice Horton is dining on the terrace while the bellboy "envelops him", as he puts it. In the close-up of the content, Richard Griffiths 's fingers hold the card by the top left corner. In the previous and following shots though, his hands are at the middle of the card and, even more importantly, there's a flyer behind it that is missing in the close-up. (00:09:25)
Continuity mistake: Peter Weller draws his automatic pistol and cocks it using the slide. He turns to the prisoner. The shot changes and as he walks behind the prisoner he cocks the gun again.
Revealing mistake: During the standoff scene in the shipyard, Crazy Kung drops Tarzan (Tyson) from a magnet crane before reactivating the electromagnet, hoisting him up again. At the points where Tarzan starts dropping and where his fall is halted, you see a hole in the electromagnet and wires connected to the actor's back. (01:06:35)
Continuity mistake: Detective Keith Lui, after some fencing with the sugar cane, finds the only way out from the apartment is to throw himself out of the window. When he is leaping down, he is upright and looking straight ahead. When he lands in front of the group of deadbeats, he is horizontal and parallel to the road. (00:09:20)
