The original American release version was truncated and had scenes moved around, making a mess of the story line. The uncut version--released overseas by Romulus--was finally restored in the U.S. by Sony in 2016.
There are supposedly two edits of the film. One is described as a 'butchered' short version & the other as longer but with better story line & continuity. The longer version is also listed as either elusive or practically impossible to get.
