Continuity mistake: At the end of the movie, when Robert has been resurrected as a tricycle, the bell and ribbon keep moving back and forth from the right handle bar to the left one.
Factual error: The movie is set in 1979-1980. You can see vehicles all throughout the movie that were manufactured after 1980.
Continuity mistake: When the two young lads jump off the bridge to escape in handcuffs, as they fall together the handcuffs disappear. (01:12:00 - 01:13:00)
Continuity mistake: During the scene on the beach, the shadows lengthen and shorten dramatically from shot to shot.
Other mistake: The object thrown (beer can?) at Jarod from the passing truck did not hit him above the neck at the bottom of his head (where his injury supposedly was). The object was thrown with an arc to give the appearance of hitting Jarod on the head, but landed closer to his left shoulder blade. (00:32:28)
Continuity mistake: When Charlotte Gainsborough has a meltdown telling the younger kid to remove the toy guitar, the kid is holding the toy differently between shots. (00:17:20)
Factual error: Close to the end of the film Michael Reed is traveling from Philadelphia to New York City by train early in the morning. The sun shines on his face from left side which is impossible in the morning, as the left side of his face faces west during that direction of travel (from south to north).
Revealing mistake: After exercising, Valerie is in bed watching the news, then the scene changes to a shot of her house showing a Honda Accord at the 2002 meeting but this model did not get released until 2008.
Deliberate mistake: The (fake) confession letter was postmarked from Ohio and sent to Allison Connor, 331 Henry Lane in Hilliard, MB 21243. No U.S. state has a postal abbreviation of "MB." The way the "B" was written in thick bold letters made it resemble a "D" - "MD" represents Maryland (where the film apparently takes place). Also, there is no current 21243 zip code in the U.S. There is a 21241 for Baltimore City and the next consecutive zip code is 21244 in Baltimore County. The created address LOOKS real. (00:50:44)
Factual error: As Ruben gets from his colleague the newspaper with the headline about the suppression of the 'douane', you can read just by his head "Mardi 17." It's 1986 as stated, and the date the news is referring to can only be February 17, when the Single European Act was signed, producing the headline shown. But it was not a Mardi (Tuesday), but a Lundi (Monday). (00:01:50)
Audio problem: When Niko is going to get the key for somewhere for Zoe to hide and then Zoe disappears he says "Zoe"? When he says it his mouth does not move but once he finishes saying it that's when his mouth moves.
Continuity mistake: The fan on the duty desk stops and starts randomly between camera shots. (00:54:10)
Continuity mistake: In the beginning, when Billy is talking to the bum (who later turns out to be Tawny), the bum has a glove on his right hand. When he reaches his right hand out to Billy and Billy gives him a subway token, there is no glove. It's back in the next shot.
Continuity mistake: During his second interview with Jack, Stone tilts his body to the right in the front shots, but remains straight in the back shots.
Factual error: If there was that much of a famine in the pack, the Omega wolves would surely have already died of hunger.
