Continuity mistake: The tiger bites the seat off the suitor's trousers, allowing the viewer to see his polka-heart boxers. When we see the tiger in the courtyard, he has a part of the same boxer shorts in his mouth. So if he bit off the seat of the trousers, shouldn't he have purple cloth in his mouth? (00:11:45)
Continuity mistake: In his cameo in this film, Tim Burton is holding something in his left hand that looks like a remote of some sort when we first see him in the background. Then the shot changes to Debbie and back to Tim, but this time he doesn't have it. Then the shot changes to Debbie again and then back to Tim, and he reaches to his far right and picks it up.
Other mistake: Towards the end where they steal the chip, they are detected and about a million security guards are all running around, yet 30 seconds later, the only security guard is one man with a shotgun. What happened to their big army of security guards? (01:41:30 - 01:42:55)
Other mistake: During the scene where Markus and Jackie are making love for the first time, as she is straddled on top of him, you can see that she that she is wearing knickers (panties).
Continuity mistake: Toward the end of the movie when the Dragons are facing the Giants for the Pennant, Hammer is up to bat and get a hit. When you see him round first base, they show a picture of the dugout, where you will find him holding a large hammer. It's tough to be at bat and on the bench.
Factual error: During the movie, Doug watches video from the previous Olympic competition. The skaters are shown performing in a darkened arena lit by spotlights. Special lighting effects like this are not allowed in competition. All competitions take place in a brightly lit arena.
Visible crew/equipment: At the surrender of the fort, as the English are marching out, Monroe, says "The fort is yours, Monsieur." At that moment, look between the two horses' heads. In the distant valley you can see what are either two tourist busses or perhaps mobile catering vans. (01:05:40)
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.
Revealing mistake: In the chase scene about an hour into the movie, Robert Loggia is shown entering the Liberty Tunnel, driving on a wet road. Note the vaulted round ceiling of the tunnel. Next, we see a series of shots of him in the tunnel, and then a shot of the sun rising over Pittsburgh as he is about to leave the tunnel. Here is the problem - the sunrise shot is taken from the Fort Pitt tunnel on a different day. Note the dry road, the barriers to the driver's left at the tunnel exit and the Fort Pitt bridge straight ahead. There is no place for the driver to make a left turn out of this tunnel. Also note that the POV is from the left lane. All the Liberty Tunnel shots show Loggia in the right lane. The next shot shows Loggia exiting the Liberty Tunnel and making a left turn from the right lane, causing a pile-up. (01:11:10 - 01:12:20)
Visible crew/equipment: In a later scene, when Kim Basinger comes to see Richard while he's in custody, you can very clearly see the boom mic over their heads.
Visible crew/equipment: At the end when Dr. Angelo and Peter are escaping the blast, just after Angelo jumps down over the facility wall and calls for Peter to follow, for a second you can see someone holding the back of Peter's shirt to help him drop down, or it might be a rigging of some kind.
Revealing mistake: When Nick returns to his apartment (after being made invisible) he immediately closes the curtains. Although he is invisible, we should see the curtains pulled closed at the point that he grabs them with his hands. Instead we see them close from the top, revealing they were closed either by a crewman or an automated process. Note: The curtains are NOT meant to be automatic in the film as we see and hear him physically close them.
