The American version released in 1973 (as Schizoid) was actually seven minutes longer than the current Italian print of that time. AIP restored some self-censored erotic footage (mostly in the orgy and dream sequences) and marketed the film to the swinging Euro/trash/nudity enthusiasts of the era.
There are at least four different edits of this film, each using different takes adding or removing scenes. The US version removed some of the nudity and the 'swan' scene. The French version had more nudity and the orgy scene was longer.
There are two DVD releases in America. The first was a 2 disc edition containing a wide screen print of the heavily cut 95 minute US version and a poor quality full screen print of the 98 minute Italian version. The newer 1 disc release has been remastered and is the full 103 minute wide screen version.
The 2009 Australian DVD from Umbrella Entertainment is taken from the same print as the 2007 Shriek Show disc. Not including the AIP logo,it runs 103:20. It contains no extras.
