Continuity mistake: When Mae and Ty meet, when Ty asks what does she think of this, Ty begins removing the lid from the bottle of wine he is holding, but in the next shot, the lid has suddenly been removed from the bottle, with his hand nowhere near it. (00:21:25)
Factual error: When Mark Felt and the FBI Director are in a car on the way to the Watergate hearings in 1972 or 1973, from the car window, you see the WW2 memorial, which was built in 2004.
Factual error: In a picture from the UN headquarters in New York in the year 2003 you see two German flags. The German Democrativ Republic hasn't existed since 1990. (01:16:04)
Factual error: The tail livery on the Concorde was not current in 1992, being first introduced in 1997. The curvy grey interior seats shown in Concorde were only introduced gradually from 1993 onwards; the film should have depicted square seating in 1992.
Plot hole: It seems highly unlikely that Lucas would be able to "mess with" Mr. Butler's application for a professorship position, or be able to accomplish what he did in such a short amount time. Off-screen, Lucas went into Mr. Butler's briefcase (foolishly left on his desk in the classroom during lunchtime) and (correctly) assumed Mr. Butler's application was on his laptop. Lucas would have to be able to figure out Mr. Butler's password (something that could take forever), find the right file on his laptop, read or scan the application to determine what he could do to mess it up, write a new answer for "qualities that make me a good teacher", and leave the classroom before anyone saw him. Lucas would also have to assume that Mr. Butler would not notice the change when he printed the application, made a photocopy, and double-checked the application before inserting it in the envelope and mailing it.
Continuity mistake: When the bald soldier gets into the cage of the apes, the amount of mud on his face changes between shots.
Factual error: The American flag displayed when Churchill arrives at the big house to meet Eisenhower has a modern day configuration of 50 stars, not 48 as it was at the time.
Visible crew/equipment: When "James" begins to repeat his "dark and stormy night" story to Carolyn it then cuts to him leaving her home, and just as Carolyn shuts the front door, the reflection of the moving boom pole can be seen on the glass window to the right. (00:31:20)
Factual error: The interior of the 747 is too narrow.
Suggested correction: There is nothing that indicates the airplane is a 747.
Continuity mistake: When Mack and Jesus are running on the river, they switch sides between shots.
Other mistake: Despite the up-to-date equipment used in the movie, Kate carries an old style film camera rather than a dslr. It was obviously so that she could develop the film later to realise her 'love'. At any rate, when going through her bag, she finds a roll of 35mm film to develop, but when the film is laid out on the light table for her to examine with a loupe, the film shown there is not 35mm. I think it was 126mm.
Continuity mistake: When Tommy and Greg get into the limo to head to the premier, there are boxes of The Room merchandise and promotional material scatted all about in the limo and filling the driver side of the back seat. But in the shots after they drive past the theater, the seat is suddenly completely empty with all those boxes disappearing. They are also missing in several of the close ups of Tommy, then back in others. (01:20:15 - 01:21:00)
Factual error: The mogul run where Molly has her accident is described as a 52 degree slope, when it should actually be a 52 percent slope (23.4°).
Factual error: Ronnie Knight is shown being released from "HM London Prison." There are several prisons in London. None of them is or ever has been called "HM London Prison" (or even the correct form, "HM Prison London").
Factual error: Before and during the Marines' arrival in Marjah, some of them are wearing Dust Goggles. These would've been first issued in World War II and continued into the early 2000s. The Battle for Marjah took place in 2010, by which point these goggles had been replaced by superior models such as ESS for some time.
Revealing mistake: Back at his NAACP homebase, Marshall meets with the boss who is already sending him to deal with another case. In the close-up of the newspaper he's reading, check out between the actor's fingers. You can tell that half of the article, which begins in English, suddenly switches into Latin 'lorem ipsum' filler text. (00:06:20)
Continuity mistake: During the beginning of the family therapy session, Dr. Beckham confirms that Ellen's father is not attending and removes the empty chair from the circle, placing it by the wall. Seconds later, the chair is back (and remains for the rest of the therapy session). (00:35:05)
Continuity mistake: Katherine Heigl all of a sudden has yellow socks when she's fighting in the last scene. (01:31:10)
Factual error: Beria was not executed until ten days after the funeral, not on the day.
Visible crew/equipment: When Renton is singing at the pub, he approaches Simon playing the piano to let him sing a line. In the shot before he places the microphone under Simon's mouth, Renton is shown moving the microphone away from his mouth, and a camera can be seen attached to the microphone, to film the shots from the perspective of the microphone.
