The prevalence of British character actors heightens the air of grotesquery. Roy Kinnear, as the Burgermeister Poppendick, brings his usual comic mannerisms into play. He is every inch the businessman who has made his pile through dodgy dealing, and is shifty, opportunistic and completely untrustworthy. He’s also utterly ineffectual as a public figure, and offers muttered asides as to the helplessness of it all. Diana Dors plays his domineering wife Frau Poppendick, one of the bellowing, comic shrews she specialised in during the 70s. She shifts with complete assurance between red-faced shrieking and saucy, winking lasciviousness, and its clear that she’s having a bit on the side with Franz.

The thickly curling horns of her wedding bonnet, shaped like indulgent French pastries, seem to mock her cuckolded husband, whose gnomish, priapically extended fez is a pathetically overcompensatory response. Donald Pleasance’s Baron is a mad, muttering recluse, retreating to the shadowy spaces of his castle, and ultimately to the shuttered nook of his coffined bed. His dank lair is covered with morbid murals of devils and skeletons, promising diverse varieties of detailed torment.

They are the outward projection of his clammy, twisted mind. Peter Vaughan’s Bishop is a guiltily perspiring serpent, desires as tightly constrained as his face-hugging costume. They are transformed into poisonous bile which his religious authority affords Papally sanctioned expression. John Hurt’s Franz, the privileged scion of the Baron, is poutingly sullen, lighting up only with the sadistic satisfaction he derives from the cruelty which his inherited power and its attendant aura of fear allows him to indulge.
