THE FIEND (Robert Hartford-Davis, 1972) ***
23 January 2010 | by (Naxxar, Malta) – See all my reviews

This is one of the more notable British horror films from the early 1970s, a stylish and generally accomplished mix of religion, psycho-drama, music and exploitation. The opening cross-cutting between a prayer meeting – accentuated by a powerful gospel song – and a vicious murder is so stunning that the rest of the film actually struggles to live up to it, though the ending – appropriately over-the-top – is worth waiting for. Thematically, the film anticipates Pete Walker's equally good HOUSE OF MORTAL SIN aka THE CONFESSIONAL (1975) – but here we get the added bonus of a typically intense performance from Patrick Magee as the religious group's fanatical leader. Ann Todd (the former Mrs. David Lean) is one of his closest collaborators – in fact, her house is a converted church! – but who has to keep her diabetic condition a secret because the intake of insulin is prohibited by her faith! Her son (Tony Beckley), a security guard and part-time swimming instructor and pamphlet distributor, is repressed and unbalanced – and soon revealed to be the serial killer of nubile girls terrorizing the neighborhood (he even records on tape the victims in the throes of death a' la PEEPING TOM [1960]!). Todd's new nurse happens to have a reporter sister (genre regular Suzanna Leigh) who, alerted to the inhabitants' conspicuous Puritanism, concludes that all is not well with the house and decides to investigate. Given the permissive era in which this was made, violence and gratuitous nudity (along with the standard prerequisites associated with such fare) contend for the running-time – and the audience's attention – with a moderately serious treatment of the subject at hand. The end result may not be surprising or even particularly insightful but nonetheless proves wholly absorbing, thanks also to its undeniable surface polish.
