Doppio taglio

An urban folklore exists that suggests that there was an alternate ending that alters the identity of the killer. An alternate ending does not exist, but the original ending was indeed re-filmed, when the initial release audience complained that the face of the killer was not clearly shown. In the original release, the unmasked killer's face was shown for eighteen frames (less than a second). Another nine seconds was later spliced into the corrected version, clearly resolving the mystery and showing the killer.

During the final court day scene, Teddy Barnes' clothes change. This is because this scene was originally shot as two separate days, but were later edited into one final court day.
