Character mistake: At the truck stop, Mark (young Damian) meets with Martin. Martin tells Mark that he had the shedding pills reverse engineered and hands him a piece of paper. The percentages of the 5 ingredients only add up to 90% rather than 100%. (01:29:25)
Factual error: Throughout the movie Danielle Chuchran wears full makeup (lipstick, eye-shadow, even mascara) despite being a prisoner. All the other female characters wear no make-up at all (or if they do, it is completely inconspicuous). It should also be noted that she is an outcast that is on the wrong side of the people who run the joint, the fact that she's the only one dolled up makes no sense other than for the very non-plot related reason that she is the deuteragonist, 'good guy' and gets close-ups.
Continuity mistake: The scene where Lilly meets the new art dealer. Lilly holds the brandy in 'his' left hand then right hand then left hand then right hand in different shots. (01:04:00)
Continuity mistake: When Killian and Ose reunite in 1957, Ose says "Come meet him" and proceeds to take Killian to meet Bisila's baby. In this shot, Killian has his hand placed on Ose's right shoulder, and Ose has his hand placed on Killian's back. In the next shot, Killian's hand is now placed on Ose's upper back, and Ose's hand is at his side. (01:26:16)
Continuity mistake: When Cross is seen inside Hank's home, he is wearing black gloves, a few moments later, in the same scene you can see that he is not wearing them anymore.
Continuity mistake: Right at the beginning of the movie, the Sergeant pulls his jeep over and headbutts a prisoner who is carrying a Danish flag, seizing it. In the following shot he has his arms open and shoves away another prisoner, no flag in his hands. Next shot, he's standing by the bleeding prisoner, folded flag in hand. (00:02:25)
Continuity mistake: The close up of handwriting on the visiting card handed over to Gert at first does not match with the close up shown later.
Continuity mistake: Right after Matt Damon wakes up from the storm, while he goes back to the base, his costume has a small backpack with a "2" written on it. After he closes the second door the scene cuts and the backpack is gone. (00:12:25)
Factual error: Eazy-E sports a black Chicago White Sox hat with a white logo early in the movie in 1986, but the logo didn't officially rollout until 1991.
Continuity mistake: After Noah's creepy "it got pretty wet here this weekend" joke at the family dinner table, Jennifer Lopez holds her tray in a complete different way between shots, multiple times depending on the angle. (00:29:00)
Visible crew/equipment: When Davis comes out from the train with the headphones on in the subway just before starting to dance, a cameraman filming the scene can be briefly seen reflected on the train door's glass. (01:08:00)
Continuity mistake: When Kate and Reggie discuss in her motel room, Reggie is sitting at the table intent on eating an apple. In the first shot he's going to put the apple in front of his mouth, but in the next shot he doesn't accomplish any action. (00:55:51)
Continuity mistake: Sue's hairstyle, as well as the texture and length of her hair, and the color, changes from scene to scene, and even at times from shot to shot. This was due to movie re-shoots.
Continuity mistake: The getaway car changes from a Peugeot Partner (1996-2003) to a Citroen C3 Picasso (2013-2017). (01:35:30 - 01:36:05)
Continuity mistake: This is near the end of the movie when Charlie Brown is running to catch the Little Red Haired Girl before she boards the summer camp bus. As Charlie encounters obstacle after obstacle he runs into the "Kite Eating Tree" and asks for help. A kite falls down and he gets tangled up in the string and he is pulled away. There is no ball of string at the end. Several cuts later when everyone is amazed that Charlie Brown is actually flying a kite and following him, a ball of string magically appears and Charlie Brown is holding it while running and flying the kite.
