Factual error: In a shot in Harlem, a Ford Econoline AVIS rental truck drives on the adjacent street. The specific Econoline van was at least a mid-90's to 2000+ model van and the movie takes place in the 70s.
Factual error: The ambulance that the junkie cop leaps out of is a mid-1980s GMC (note the 4 square headlamps), though the film takes place in 1971. (00:35:55)
Factual error: At one point, Frank Lucas is speaking on a public telephone. Visible in the background is a poster with a web address on it (ends in .biz).
Factual error: As the camera is following behind the red Bronco, at the right side of the screen a modern, white NYPD Chevy Malibu is briefly seen. (01:01:40)
Factual error: When Frank puts coins in the pay phone, a blue label states it is a NYNEX phone. It is 1970, yet NYNEX wasn't formed until 1984. (00:20:45)
Revealing mistake: When the cops bust the lab where the dope is cut they push a big man in a white T-shirt. The blood pack on his back is very noticeable.
