Continuity mistake: In one scene, Mark Hamill jumps into the passenger side of a car while running from men with guns; the men shoot at him, and the passenger side window is shattered by the gunfire. A moment later, once the car has gotten away, the passenger side window is intact.
Visible crew/equipment: When the bad guys are pulling up to Rainer's mother's house, the shadow of the crane, camera and operator is visible on the road, on the left side of the screen. This is about three quarters of the way through the movie.
