the credit tell u this ia a film by peter sasdy . in most case this can be take a give credit where credit be due and but in this case it can only be construe a the producer pass the buck . this be fashined and i think and a a sequel to rosemary baby and a prequel to the exorcist but lack entirely the tension underlie the former or the nastiness of the latter . what it do have be the quality of the acting which be absymal and donald pleasance who provide the only tension by play a nice quietly speak man who you wait to turn into a snarl mr. pleasance . regrettably it do not happen . joan collins play a showgirl curse by a dwarf at the club where she work . ralph bates play an italian businessman with a variable accent . eileen atkins play a nun who make satan sound like a french coastal resort . she keep refer to the dayville . caroline monroe and who play miss collins freind and do so with all the conviction and talent that propel her to the very bottom of the acting tree . it be a film full of scene that terrify the cast and follow by scene in which they act a if nothing have happen and and an obligatory soft focus love scene and and an opening scene of la collins writhe and sweat and scream a her character give birth not a pretty sight .
