Goodfellas (1990)

Factual error: In one scene we are introduced to Idlewild Airport in 1963. We're shown a couple of aircraft in flight and one of the aircraft is a Boeing 747 in the livery of KLM Royal Dutch Airlines. The Boeing 747 didn't enter commercial service until 1969.

Revealing: In the scene where Karen is too afraid to accept free clothes from Jimmy and speeds off, the yellow NY state license plate falls from the parked car to reveal the modern white one underneath.

Continuity: When Henry Hill is in jail and talking with his wife, the child is playing with a stack of coloured toy blocks. The order the blocks are stacked in change in different shots.

The end of the film states that Jimmy Conway was eligible for parole in 2004. He died in prison of lung cancer in 1996 before getting the chance.

In the scene where they all went to Tommy's house and his mother is making dinner for them, the lines during that scene were made up by the actors themselves.

Both of director Martin Scorsese's parents are in the movie. The old lady that plays Tommy D's mother and the man who shot him when he thought he was going to be made.
