Continuity mistake: When Bob finds Scott and Kate at his office with the money and runs at them, he slams into a frame at the end of the hall breaking the glass. It cuts to a different angle and suddenly he's slamming into it again but the single sound effect is still playing. (01:14:41)
Factual error: Since the movie was set in the 60s, David Senak couldn't have gotten in trouble for shooting the man running away. In the 60s, the police could legally shoot any criminal running away. This didn't change until Tennessee v. Garner in 1985.
Other mistake: When the Polish police officers are shot in the van, there is no blood splatter at all. Two seconds later there is blood on the wall. When the guy in the middle is shot in the chest, blood sprays almost one meter above and behind him on the wall. (00:33:25)
Continuity mistake: Kate at the beginning of the movie asks Demerius, the kid who is reading a manga, to read some of it loudly for the whole class. When she addresses him first, the book on his desk changes position between shots, repeatedly. (00:01:20)
Continuity mistake: When the soup is about to be served, you see the horns blowing to introduce Victoria, and you can see all of the footmen lined up already with trays of soup, but in the next shot, it shows that they are just starting to march in to line up with their trays of soup. (00:10:45)
Factual error: The man cutting through the door is pictured holding a torch, but that type of torch is not a cutting torch. You also see a showering of sparks as though a grinder is being used. (00:42:00 - 00:43:00)
Continuity mistake: When Megan is outside the supermarket asking people to sign her petition, a woman walks up and begins writing on the clipboard. In the first shot, the cap is on the back side of the pen. From the next angle, the woman is scribbling and lifts the pen to show the cap covering the tip that she was "writing" with.
Visible crew/equipment: When Detective Hole enters the murderer's cabin you can see somebody running in the snow outside.
Continuity mistake: Gardner Lodge first takes a bite from the corner of the peanut butter and jelly sandwich and sets it back on the plate. The camera angle changes and when he is seen holding the sandwich again the bite is now taken from the middle of the sandwich. (01:28:55)
Audio problem: During Beca's performance of Freedom, she is singing with Cynthia Rose. During the little chorus pre-verse (before they put their hands in the middle), you can hear Beca's voice singing the lyrics but Anna Kendrick's microphone is nowhere near her mouth. Her lips don't even match it.
Factual error: Just after feeling the explosion from the south tower, Eddie's watch shows 17:37 whilst others and himself are stuck in the North tower elevator. The planes hit the towers in the morning. (00:35:00)
Character mistake: Set in Texas, the Sheriff threatens the wrongdoer with the gas chamber. Executions in Texas at that time were all by electrocution, namely by "Old Sparky," the electric chair. Texas has never used the gas chamber for executions.
Factual error: The black leather chair of the Home trust banker is more modern than the movie setting in 1922. (00:59:35)
Factual error: When the bank robbers pull the money out of the vault, they claim all the cash is from 1982. Yet most of the bills have large faces, which was introduced into rotation in 1996.
Factual error: Engine 463's firebox is seen in a close-up, revealing a cast in date mark of 1914. The caption near the start says it's set in 1892. (02:02:00)
Continuity mistake: After Hutch is buried, Dominic leaves to catch up to the other two, limping with his right knee held rigid. An aerial shot is then taken showing Dom limping on his left leg instead.
Factual error: In the beginning of the movie, during Dickens' visit to America, you can hear them playing the melody from the song "I'm a Yankee Doodle Dandy" written by George M. Cohan in 1904. This was 61 years after the events in the movie. In the ending credits they cite this as "Yankee Doodle Dandy" which was written many years before. But, that was not the melody that was being played.
Factual error: Allegra was said at the end of the film to have died aged 10. She was actually 5 years old when she died.
Factual error: No matter how sophisticated the STEM chip is, it would not enable Grey (Logan Marshall-Green) to go from a completely horizontal position to a completely vertical position in one fluid motion, without bending his knees, and he does this several times in the film.
Factual error: The accident takes place the night of July 18, 1969, and they show there being a full moon. That night the moon was actually waxing crescent with only 14% visible, and set at 10:27pm while the accident happened about 12:45am, so there was no moon in the sky anyway.
