At the construction site after the car chase, Peter has tricked a pair of government agents into driving off a sheer drop. Their car drops offscreen and a moment later a giant fireball rises into frame, implying that the car struck something solid and exploded.
Soon after, Peter drives a stolen Cadillac off the same precipice and his car lands in a body of water with no sign of the exploded car or what it might have hit to make it blow up.
Peter shoots out of the open car window to help Gillian, this causes the crash that Hester ends up involved in. After Gillian's shock it Pan's to Peter, his face shoved against the now closed window, it flattens part of his face then lifts and wrinkles the rest. When he gets out to run to Gillian to shot the guy grabbing her, the car door swings out and you see the window is once again open...
When Peter Sandza's car is chased by the police on the Pier, you can clearly see the head of a crew member on the left of the screen. The camera is moving left to right, and the technician was probably running for the traveling beside the camera.
Early in film, in tracking shot of Robin and Peter at the beach cafe, a young man steps from the water nude and is seen between the father and son. As the young man emerges back into view from behind Peter, he can be seen covering his groin with his hands.
When Hester realizes the heavy-breather she's been teasing on the phone isn't a prank call, but her lover Peter, who's in trouble and needs her help, she abruptly hangs-up the phone, then scrambles up the stairs to change clothes. However she forgot to ask him where he is. The next scene is Hester driving Peter in the VW van.
