The producers kept this film tamer than the first one so they could secure an "R" rating and bring in a larger audience.
As with Ilsa la belva delle SS (1975) the film was refused a UK cinema certificate by the BBFC. It was finally passed fully uncut for DVD in 2013.
Musical theme by Tristram Cary for Hammer production Exorcismus - Cleo, la dea dell'amore (1971) can be heard both in opening and closing scenes of this film.
