Continuity mistake: Before the Princeton interview, Jeremiah has his shirt untucked and he tucks it in when asked to. But when he is standing at the door with the interviewer, his shirt appears untucked, then tucked, and then untucked again, then tucked in again.
Factual error: Company of Heroes is in the timeline of 1944-45. Soldiers are wearing the flag patch on their uniforms which have 50 stars on them, not 48. There were only 48 states in the U.S. back then.
Continuity mistake: As Lex and Joker are talking on the bridge between two towers of Arkham Asylum, Joker is shown standing in the middle of the bridge. But when the guy on the intercom announces there is an escape going on, the camera changes angles and suddenly Joker is right next to the edge. (00:19:20)
Audio problem: When Hayes and Nick are fighting at the end, Hayes grabs Nick and says "get over here", but his mouth never moves and his teeth are clenched the whole time.
Plot hole: They discover a "not so well hidden" microphone in the car that tells them the "man" is listening to them, but it is ignored throughout the rest of the movie, especially when setting up a video loop to cover their extracurricular activities. (00:30:00)
Continuity mistake: In the scene where Heather runs through the fairground she grabs onto the back of the Ferris wheel seat and is taken up in the air. Leatherface throws the chainsaw at the cop and the next shot shows Heather coming back down the other side of the Ferris wheel. But she should be on the inside of the carriages as it just spins round on an axis. These kinds of wheels don't "twist" at the top otherwise the rider would just be staring at the inside of the wheel the whole time.
Revealing mistake: At the end of the film when John Moon is digging a shallow grave for the dead girl (who has been dead for days, and spent additional days in a freezer also). You can see the dead girl breathing by the way her arm is moving on her chest. (01:46:00 - 01:47:00)
Factual error: A concrete barrier is shown around the White House in the 1960's. This was not put into place until the 1980's.
Continuity mistake: In the hotel, at Gagamel's room when Clumsy suddenly opens the food lid and bonks the room service guy. The lid falls at the right side of the door, but in the next shot, when Gagamel opens the door, the lids is on the left side. (00:55:55)
Continuity mistake: In the scene when Papi is in the back of the white Fodge driven by Stig, the Ford Bronco driven by Bobby crashes into Stig's white Dodge twice - both headlights are smashed out. Once the Bronco goes into the ditch and comes back out, the passenger side headlight isn't broken.
Continuity mistake: Amanda warns the team that if they breathe a word of her secret life, she will hurt them "in ways that haven't been invented yet." The camera cuts to the crew and Savanna is sitting up, next to Melissa. In the next shot, Savanna is right above Ben's right shoulder.
Factual error: At the end, Josh and Nat both run onto the Eurostar platform when they do not have a train ticket - this would be impossible, since there are ticket barriers and security.
Factual error: Halcombe takes a left turn to park in the parking lot of the Army/Navy Surplus store on 4th Avenue. This means he was approaching from C Street, which is a one way street in the opposite direction between 4th and 5th Avenue. (00:15:00)
Visible crew/equipment: After the jewelry heist, outside in the backyard when Ross looks for Parker, the camera crew is visible through the window, about three or four shadows appearing on the window reflection. (01:42:35)
Continuity mistake: Jack puts his hat back on as Mr. Ginormous is challenging him to a fight. He keeps his hands on his hat like he's trying to hold it on in a wind storm. The angle changes to behind him and suddenly his arms are down at his side. (00:43:20)
Continuity mistake: Lamenting his failed SOS call, he retreats to the cabin where he pours himself a drink. After pouring his drink, he puts the bottle down and the bottle is about a third full. As he drinks from the glass, the bottle changes to be more than 1/2 full. (00:23:00)
Continuity mistake: When Otto is sat down at his HQ, telling the Vet and Kisko that they would become steak, Otto is holding the newspaper in his hands, but in the next shot, the newspaper has disappeared, and he stands up, holding the steak. (00:20:10)
Continuity mistake: We discover that because time is non-linear in the Further, it was Josh's spirit who was the one knocking on the door in the original film. However, the knocks we see Josh make in this film don't quite match up with the original film. In this film, he knocks many times frantically, whereas in the first film, we only hear a few faint knocks in rounds of three. (The film tries to mask this by inter-cutting footage from the first film to illustrate the point, but it still doesn't quite match up).
Other mistake: The driver for the general at the end of the movie is referred to as captain, but is in the credits as Major Carrie Farris. (02:09:50 - 02:15:35)
Continuity mistake: In the barrel riding scene just after Kili is shot in the leg, Tauriel arrives carrying her bow in her left hand. In the next shot the bow is in her right hand: she nocks, draws, and shoots with her left hand. (00:50:20)
