Continuity mistake: Late in the movie, when Anya says goodbye to Patrick, she takes off her wedding ring and puts it on the table before leaving the café. In the next scene, her wedding ring is visible on her hand throughout her call from the phone booth.
Continuity mistake: When Laurence asks Colin for a cigarette in the screening room, he has it between his fingers when Colin lights it, but when the shot cuts, his fingers have disappeared from around the cigarette. (00:45:30)
Other mistake: At the beginning, the arrival board has the cities listed in alphabetical order, but "San Francisco" comes after "San Jose" when it should come before it.
Continuity mistake: The licence plate of the Toyota Camry that Dagny Taggart is driving changes from a red Colorado plate to a Wyoming plate. (01:25:26 - 01:26:45)
Factual error: The young priest sees images of a red-eyed horse, but later, it is referred to as a mule, which looks much more like a donkey.
Visible crew/equipment: During the torture and murder of Troy there is a moment when Jamie, unable to watch the violence, sits in the kitchen with accomplice Mark Haydon. Jamie and Mark sit in silence at the kitchen table and the film cuts between close-ups of them. In the two close-up's of Mark you can see the boom microphone reflected in the glass of the kitchen cabinet near his head. This happens twice and the microphone lingers both times. (01:15:29)
Other mistake: In the hospital, Barrett had his right arm in a sling and his lower left leg in a cast. When the police/ detectives were trying to find Barrett, one detective said Barrett could not have driven himself somewhere because he had "a cast on his leg." The cast was on the left leg, so Barrett could have driven using his right leg, as usual. Maybe he couldn't have driven with a cast on his right arm, but the detective gave the wrong location of the leg cast. (00:50:30 - 01:13:45)
Deliberate mistake: The driver's side mirror would not be able to capture the view of the store that Monique is robbing - the mirror is slightly angled towards the rear of the car, plus Arthur's car is parked too close across the street. (00:00:33)
Continuity mistake: At the start of the film, when the bus driver helps the man in a wheelchair onto the bus, his hat disappears then reappears. (00:05:00 - 00:06:00)
Continuity mistake: When Paul is chasing Bozlovski at the port, he repeatedly shoots through his passenger side glass, destroying it. A few seconds later, the glass can be seen undamaged when both cars are banging each other.
Continuity mistake: In two scenes featuring close-ups of the fireplace days apart, the same logs are burning.
Visible crew/equipment: While Maria Leon is talking in the corridor to the head of the house she is applying to, the tip of a microphone appears on the top of the picture. (00:11:10)
Factual error: When Andy is headed to Mr. Simon's house, a white 90s Lincoln Town Car can been seen in the background, out of place for the 1965 setting. (01:31:45)
Revealing mistake: While Lynn is driving, the scenery outside the driver's side window goes white a few times and, other times, with intermittent specks of green tree leaves/shrubs. The white-outs are too low to be representing the sky. For a period of time, the lower third or so of her side window is a horizontal white bar. (00:02:20 - 00:03:38)
Factual error: The car doors wouldn't protect Adam and the other police officers from being shot - they offer no protection against bullets.
Revealing mistake: When Donovan witnesses a fatal traffic accident on a rainy night, he suffers a mild heart attack and collapses in the street. Although he's lying on his back, unprotected from the downpour, surrounded by rain striking the pavement in both foreground and background, closeups show that no rain strikes his face, his felt hat, or his clothing. (00:12:20 - 00:12:50)
Continuity mistake: The designated Pope has just been visited by a physician. Three cardinals want to take a stroll outside for some sweets and arts. One of the cardinals stands and rebukes them; you can see that the cross on his chest has its chain caught in a button of the vest. During the rest of the scene the chain is caught in that button in the closer views and is loose in the wider angles. (00:23:50)
