Mistakes
When Johnny Depp and Al Pacino are driving in the car (I believe it's the first time Depp drives Pacino around), they pass an MCI billboard - the one that continually updates the figures as to how much money you'd save if you had MCI long distance phone service. MCI didn't exist in 1978. See more...
Trivia
Joe Pistone maintained his cover so convincingly in real life, the Bonanno Family seriously considered "making" him before it was revealed he was an FBI agent. See more...
Donnie Brasco (1997)
Directed by Mike Newell, starring Al Pacino, Anne Heche, Bruno Kirby, Johnny Depp, Michael Madsen (add more)
Donnie Brasco mistakes
Factual error: Towards the middle of the film,Pacino and Depp are walking downtown, there is alot of traffic and some of the cars are "post 1978" model . One in particular caught my eye, which was a mid-80's Ford Taurus (even the model of the car didn't exist in 1978).
Visible crew/equipment: In the scene where the two are crossing the bridge in the car, the camera crew can be seen several times as reflections in the windscreen when the shot changes to outside the car.
Donnie Brasco trivia
Throughout the entire movie, Donnie Brasco is seen wearing a wire device. In the actual book, Agent Pistone was said to only wear a wire maybe a few times in the 6 years he was undercover.
Joe Pistone maintained his cover so convincingly in real life, the Bonanno Family seriously considered "making" him before it was revealed he was an FBI agent.
The scene in which Joe Pistone bets his children that they can't make it through breakfast without saying three words (and his daughter replies "You lose") is a reference to a similar bet made to, and the exact same reply from, president Calvin Coolidge.
