American Graffiti (1973) - 5 major mistakes

Factual error: In one scene a parked car is sitting along the street - it is a '67 Chevy. Yet the film is set in 1962.

Continuity: In the first part of the film, when John Milner is cruising he pulls up next to a car and chat to Zuto. When he sits back in the driver's seat after the conversation, you can see Mackenzie Phillips sitting in the passenger seat facing Milner for a split second before cutting to the next scene. She shouldn't have been there.

Other: During the film the black 55 Chevy driven by Harrison Ford has nice wide chrome wheels, however after the crash scene at the end of the film when the 55 Chevy is upside down, you can clearly see the wheels are now simply standard steel rims spray painted silver.

Visible crew/equipment: As Milner and Carol get out of his hot-rod to vandalize the girls' stopped car, a bearded man with a mustache can be seen in the car window's reflection as it's being rolled up. The man is wearing a white long-sleeved shirt with what appears to be a maroon sweater-vest. I believe the man to be George Lucas, as he appears to be directing in an upward motion with his left arm.

Revealing: When Falfa's Chevy flips over, we can see that it has no fuel tank at all in it. However, in the next shot the fuel tank re-appears and explodes.
