The original UK cinema version was cut by the BBFC to edit some of the gore from the murder scenes, including the decapitation, and various shots of dead bodies. The cuts were restored in all later UK prints.

Francis Coppola's director's cut has been aired on TCM as recently as 2024. It removes a scene from the original release in which the villain kills a poacher with the ax. The version on TCM also cuts the prologue with the psychiatrist.

Some prints of the film contain a prologue in which a psychiatrist would give the audience a test to see if they were stable enough to withstand viewing this film. This prologue has been removed from the television versions, reducing the running time from 81 minutes to 74 minutes. Many video releases of this film list the 81 minute version on the box, but actually contain the 74 minute version.

The Slingshot DVD is a fabricated 3D version of the film that is viewable in razor3D system. This is an artificial 3D gimmick as the film was shot in standard flat format and not in 3D

There is a DVD with a computer colorized version.
