Continuity mistake: In the scene where Handratty is arresting Frank in France, Frank is about to run out the door with the cheques and Handratty says he will be killed if he runs out. As Frank walks back toward Handratty , Frank's arm position as he's holding the cheques goes from right-over-left to left-over-right as the shot changes, and the cheques are piled in his arms completely differently from one shot to the next.

Factual error: In the scene where Frank Abagnale is arrested in France, on of the police cars has a license plate that ends with 'PP 41'. Now the last two digits are a code for a particular French district ('departement') and the two letters indicate the age of the car, i.e. the first licence plates ever had the letters AA, then AB, all the way through to ZZ and most recent licence plates have three letters. For this particular 'departement' the highest possible letter sequence would have been HH for 1969 and JB for 1970. So this particular car, or its license plate, is much more recent than 1969 or 1970. (01:57:45)
Factual error: When the family is leaving the home they had just sold, the shingles on the roof are laminate shingles which were not invented until the 1970's. And that particular style was not developed till the 1990's. (00:16:20)
Continuity mistake: When Frank Jr. Is getting fitted for his pilot's uniform (because he lied and said he lost his other one), after the tailor finishes and tells him the cost, there are only two rank bars on his sleeves. Then, when he walks out in the uniform, there are three bars on the sleeves. Considering he says he lost his uniform in his first week as a copilot, he wouldn't have been given an extra bar before leaving. (00:34:35)
Continuity mistake: There is a scene where Leo is at a hotel and meets Jennifer Garner, the 17 model. Then when he is recruiting flight attendants at a school, you see Jennifer Garner again but this time as one of the school girls.
Continuity mistake: When Frank is having lunch with his father and offers him a Cadillac, in some shots Frank's right arm is over the table, but in others he has both arms hanging.
