Public Enemies (2009) - 12 mistakes

Factual error: Early in the movie, during a bank robbery, there is an FDIC sign beside the teller. Dillinger's bank robberies were mostly in 1933, he was arrested in January 1934. The FDIC was not enacted until January 1934, making it impossible for the bank to have been insured by the FDIC during the 1933 robberies. Additionally, in the same robbery, the teller displays $5 bills that are the current format (multiple colors, offset picture, larger numbers) which would not have been present at that time.

Factual error: In one scene, focused on a car on the street, you can look closely and spot a modern-day vehicle in the background. http://failblog.org/2009/07/19/public-enemies-fail/.

Factual error: The film is set in the 1930s, but when there is a closeup of a sheet of text (a conversation between Billie and John), it is typed out in a computer font (which did not exist) as opposed to a typewriter.

Continuity: When John Dillinger escapes from jail by stealing a police car, the car slowly stops at a traffic light and we can see officers to the left of John (and the car). In the overhead shot of the car and the traffic light, the officers have disappeared from the sidewalk, but in the following shot the officers are still there.

Continuity: When Dillinger is looking at his watch just before going to the movies, you can see that the time is 6:00. Close-up of his mum's photo, and the time is now something like 6:25.

Factual error: When Special Agent Winstead is leaning over Dillinger to hear what his last words are, you can see that he's wearing modern-day contact lenses, in 1934.

Revealing: In an aerial shot of Lincoln Ave in Chicago outside the Biograph Theater the rubber mats laid on the road to look like 1930's brick streets only cover the middle 1/3rd of the street. On the outside 2/3s the street is modern asphalt and shows striping tape for bike lanes.

Continuity: When John gives Billie her mink coat, the amount of wrap paper coming out of the corners of the box differs between the front and back angles.

Other: When Dillinger is being flown back to Indiana he has a mustache. As he is leaving the plane, the mustache is gone.

Revealing: In the scene where Dillinger breaks out of jail in Indiana, there is a shot of the getaway car and its license plate, and you can see that the license plate says "Historic Vehicle" on it.

Factual error: During the movie Dillinger talks with Baby-Face Nelson about a train job. The train is visible in the background. The train however is the Union Pacific locomotive 844. This locomotive was not built and delivered to the Union Pacific until December 1944, 10 years after Dillinger was killed.

Continuity: When Depp is in the cinema, with the audience looking left and right without seeing him, in a wider shot he's worried, then slowly breaks into a wry smile. We then cut to a closer shot, and he's suddenly looking serious again, before smiling once more.
