Rumour has it that Dario Argento's original cut of the film ran almost an hour longer and that the version which was finally released, has been heavily re-cut and changed by the producers to assure the film's appeal to wider audiences.
Although there's a phantom mask on the theatrical poster, this is actually the only film version of Gaston Leroux's novel in which the Phantom wears no mask at all.
Cinematographer Ronnie Taylor has worked on three other adaptations of Gaston Leroux's novel "The Phantom of the Opera". He was cinematographer in Dario Argento's previous Terror in der Oper (1987), as well as camera operator in Brian DePalma's Das Phantom im Paradies (1974). He also did the cinematography for Skinner (1991), which is considered to have been inspired by the novel.
