Revealing mistake: During the bedroom scene with Felicity and Fat Bastard you can clearly see the air hose that fills his suit when he rolls over in the bed. (00:49:10)
Other mistake: When Catherine breaks into Crown's house, her assistants immediately get to work on the security panel. When the first assistant touches the panel, it falls off the wall and he has to quickly push it back into place.
Factual error: Ashley Judd is convicted of murdering her husband for the insurance money and that would make it a first degree murder charge (first degree meaning she planned the murder). Because of that there is no way she would have been eligible for parole after just 6 or 7 years.
Continuity mistake: Terence Stamp takes out a pursuing vehicle by reversing his own car into it at high speed and pushing it over a cliff. When he subsequently drives off, amazingly there's no damage at all to the rear of his car. Shortly before, it is peppered with gunshot holes which mysteriously disappear.
Factual error: A copy of Miles Davis' album "Tutu" is sitting on a counter. Odd since the recording wasn't made until 1986.
Continuity mistake: When Sly is in the attic, and the fake power dude comes up to kidnap him, Sly uses a ski to "hit him in the gonads". But if you look closely at his face, the guy who was hit in the nuts wasn't the same guy that fell down the stairs.
Continuity mistake: When she goes through the lasers it takes 2 minutes to get to the mask, but it only takes 30 seconds to get back.
Continuity mistake: When he is playing Tetris, he is playing a different game every time. (00:43:35)
Factual error: In the scene where the fire department responds to the fire, the engine is 42. Yet all the fireman's hats say 6. The engine company, station etc. would all be the same number so their helmets should have also been 42.
Factual error: Tom Hanks refers to an Intensive Care Unit, and although a few physicians had already discovered the practice of separating the sickest patients into a separate ward in the 1930's, the term Intensive Care Unit was not yet in use.
Other mistake: At the start of the film where Detective Dooley and Jerry-Lee are getting ready for work, we see Dooley climbing out of the shower, but in the reflection in the mirror behind him, we see him emerging and can clearly see his under-pants which are bone-dry. (00:00:32)
