Errors in geography: The final scene looks like Foley Square - downtown NY with the New York City Hall in the background - not anyplace in New Jersey, where Sarokin would be sitting.
Continuity: After the shootings in the bar are shown the first time, the exterior shot shows the traffic light at Madison Ave. In the later flashback, there is no traffic light.
Errors in geography: Although the scene takes place in New Jersey, just before the car crashes, it passes a Shoppers Drug Mart advertising sign: SDM is a chain of drug stores found only in Canada.
Continuity: When Rubin first goes to jail he is told that he can't keep his watch or wear his own clothes. Later, while he's in jail, he's obviously wearing his watch.
Anachronisms: The CLRV streetcar that whizzes by in the background when Lesra sends his first letter to Rubin Carter in Toronto, wasn't introduced to Toronto streets until 1979.
Continuity: When Rubin places the Polaroid photograph into his book, he closes it so that he is looking at the cover. In the next shot, as he puts the book down, the cover is facing the floor and he is looking at the back.
Anachronisms: When Larsa, Lisa and the two Canadian men get out of a cab in downtown New York to meet with Ruben's Lawyers, the cab shows the starting fare as $2.00, the fare in the 1980s was $1.10.
Revealing mistakes: When Carter's Federal Court victory is announced, jubilant inmates hurl waste paper from the cell decks to the floor below. In the background a huge pile of waste paper can be seen, the obvious residue of previous takes
Factual errors: Credits at the end of movie state that Rubin Carter is the only boxer to have received an honorary championship title belt from the World Boxing Council in 1993. This is incorrect as the boxer Joey Giardello also received an honorary championship belt at the same banquet in Las Vegas.
Factual errors: In the first featherweight fight sequence, the radio sportscaster pronounces the Pennsylvania city name, "Reading," as "reeding" (long "e" sound), but it is correctly pronounced as "reding" (short "e" sound).
Continuity: When Lezra visits Rubin in prison and they are talking at the table, Rubin is shown holding a photo in his hands. The reverse shot shows Rubin with his hands clasped and the photo sitting on the table.
