Visible crew/equipment: In the opening murder scene watch when the man is stood outside the connecting train car doors, there is a shot from behind, moving in on him, and if you look out of the left window you can see a set of yellow ladders. This is set equipment and the train obviously can't be moving. (00:02:20)
Factual error: The Major and the band are (correctly) summonsed to appear before a magistrates' court for driving without insurance, but then appear before a judge in full robes. Judges do not sit in magistrates' courts.
Factual error: Jennifer Lawrence uses a Bic lighter that has a child-proof safety device on it. The film is set in 1976. Bic lighters did not have safety devices on them until the 1990's. (00:57:25)
Revealing mistake: When Louis is trying to get Lester to apologize to Cleo after hitting her, lots of extras on the sidewalk and across the street can be seen watching the whole scene being shot.
Plot hole: At the end of the movie we discover that the main character (Claire) was in the plane crash and was sitting next to Eric as the plane started to go down. However at the beginning of the movie( before we are supposed to know Claire was in the crash) Eric can be seen but Claire is not next to him. (00:01:10 - 01:19:20)
Continuity mistake: At the beginning of the film when Georgiana is talking with her mother about her engagement, the curl running down the back of Georgiana's neck disappears and reappears multiple times.
Character mistake: During the seminar, Professor Rohl tells students that only 19 workers of Auschwitz were sentenced (in 1966). During the first trial of Nazis from Auschwitz, 39 were sentenced, including 23 persons condemned to death. The trial was in 1947 in Krakow.
Factual error: When Caroline is opening the envelope from Dr. Henry, she removes a wad of cash. They are modern bills; the large corner numbers weren't introduced until the late 1990s. (00:32:30)
Revealing mistake: The raid took place at Xmas in 1951. In homage to this fact, the characters wear big coats and one of them even rubs his hands together and goes "Brrr." Yet the movie was filmed in the height of summer. Trees in the background of scenes in London are full of leaves, we never see any mist in exhaled breath and the lighting levels and shadows indicate a high, bright sun.
Plot hole: Blackbird and Ritchie fake their deaths in order to lure Wayne and Carmen out of hiding. What was the point of pursuing Wayne and Carmen? The only reason they wanted the couple dead was to prevent them from testifying. The problem is .if Blackbird and Ritchie were "dead", the case would be CLOSED. Carmen and Wayne wouldn't be testifying anyway. So why go to the trouble of killing them? It makes no sense.
Audio problem: The day after Operation Mardonius, when the first set of bombs explodes you first see the explosion and then hear it after a second, then as the last bombs explode you both see and hear the sound at the same time.
Factual error: When the captain is arguing with the Armed Services Committee chairman, Homeland Security is mentioned. However this movie takes place prior to Desert Shield, and the Department of Homeland Security wasn't created until over a decade later.
Continuity mistake: When the brothers are standing on the rocks on the beach, the clouds change back and forth behind Stephan.
Continuity mistake: When Ronald's girlfriend gets up at the breakfast table, and tousles his hair, Ronald is holding a glass of milk in his right hand. There's a cut to a wide shot, and Ronald is not holding the milk. There's not enough time for him to have put it down.
Continuity mistake: In the scene where Sam is talking with the person in the cemetery, while they are sitting side by side on a bench. In one shot there is an object on his left shoulder and it is missing in the next shot.
Visible crew/equipment: When Tibby is talking to Lena on the phone about the man in her art classroom, you can see a crew member's face reflected on the glass window.
Other mistake: In the scene of the wedding rehearsal dinner, when everyone is toasting, there are people outside the restaurant's door just standing there looking at how the scene is being shot.
Revealing mistake: In the opening scene, when Van Damme kicks an opponent onto the boot of a London Taxi Cab, you can see the dent from previous takes.
Continuity mistake: During the scene that Bo and Sam kiss, his hair changes between shots. From the back, his hair is completely pulled back. From the front, his bangs are down. (01:27:20)
Revealing mistake: When Ricky and Brandon are on the ferry, the camera shows Ricky reaching down to grab Brandon's butt and then it cuts to Chance and Eddie. If you look closely, Ricky and Brandon are re-creating the scene they just performed.
