The Film: Roman Polanski’s brilliant shocker about a nice young couple (Mia Farrow, John Cassavetes) who move into an apartment block and find the neighbours like to engage in devil worship.

The Neighbours: Creepiest of the lot are little old dears Minnie (Ruth Gordon) & Roman Castevet (Sidney Blackmer). Potions and tonics, quaintness and consideration are the deceptive public face of the evil seniors at the head of a conspiracy involving devil rape.

How To Avoid: Form your own alternative religious sect but make yours bigger and noisier. Do songs, do chanting and designate a giant teddy as your alter, which you and your thousands of loyal followers can dance around.
