Donnie Brasco (1997)

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).

Continuity mistake: When Depp and Pacino are in the bow of the yacht Depp got from the FBI, Depp puts his glass on the rail of the boat and it is in shot. In one shot of Depp the glass is gone and the next time you see Depp its back.

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.

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.

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.

Trivia: 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.

Sonny Black: You know what we do when we find that rat, right, Lefty?
Lefty: 'Could be I found him already.

Question: Did the real Lefty actually have "cancer of the prick", as was claimed in the movie?
