Deliberate mistake: When the CA. trooper is at the front of her car, the Arizona license plate is shown. In 1989, Arizona began issuing a single license plate and that plate is always on the back of the vehicle. This is deliberate, as the remake follows the original movie shot by shot, and there the trooper checks the front license plate.Dennis Gannon
Visible crew/equipment: When Marion is dead, you can see the camera panning back reflected in her eyes.
Revealing mistake: As a homage to the original; when Norman carries Marion's dead body, wrapped in the shower curtain to the car, you can see her bra strap through the curtain.
Question: When private investigator Milton Arbogast is attacked on the stairway, this film inserts two non sequitur pieces of footage right in the middle of the attack sequence: Just as Arbogast's face is slashed twice, a shot of a virtually-nude woman wearing a sleep-mask is inserted for a split-second, followed a moment later by a split-second insert of what appears to be a small calf standing in the middle of a road in a rainstorm. What is the meaning of those two inserts?Charles Austin Miller
