Factual error: Some characters are shown at Paddington Station and in the background the train shown at the platform is a 1920s Southern Railway green electric driving coach. Paddington at the time of the film was home to the Great Western Railway which never operated electric trains and never used green livery on carriages. Furthermore the carriage was issuing copious amounts of steam (accurate for the period and venue) but impossible from an electric train.
Factual error: When Jack jumps out of the plane as a flying Elvis, he pulls both chutes to open. If both opened as they should have because he pulled both lines, the parachutes would've become twisted and he would've died on impact with the ground.

Factual error: Ron Pearlman plays a state police captain named "Captain Soames". On his uniform he has both captain's bars on his shirt collar and sergeant's stripes on his upper shirt sleeves. He would not hold both ranks and would not keep the sergeant's stripes on if he had been promoted to captain. He also would have gone through the rank of lieutenant (one bar) prior to becoming a captain, so he would have had plenty of time to take the stripes off his uniform.

Factual error: In the scene where Redford's character enters through the secured entrance with the stolen key-card, it shows a printer printing the time he entered. Then after his walking and getting up to the top floor and trying to get past the voice verification system and having to do it twice, they show the same printer printing the time he passed that checkpoint, and it was only one minute later than the previous time. Even though seconds are not shown, all of these actions must surely have taken longer than 1 minute and 59 seconds.
Factual error: The titular character, "the bellboy" works at a hotel in Venice and has an italian accent, but whenever he actually speaks in Italian it is obvious that he is no native speaker, he really butchers his lines in the language.
