The Hellfire Club is a 1961 British film directed by Robert S. Baker and Monty Berman and starring Keith Michell, Miles Malleson and Francis Matthews, with Peter Cushing in a cameo role.
The debaucheries of the Hellfire Club strike an extremely jaded note, Kai Fischer's hoydenish heroine is peculiarly resistible, and only Adrienne Corri's two-faced Lady Isobel makes a creditable impression.
Keith Michell, whose athletic prowess evokes happy memories of Douglas Fairbanks, Snr., contributes a tireless performance as Jason, Kai Fischer, sporting a daringly low neckline, is a tantalising, though steadfast, Yvonne.
Adrienne Corri scores in contrast as the haughty, two-faced Isobel, Peter Arne makes a thoroughly evil Thomas and Bill Owen introduces some down-to-earth humour as Martin.
The scenes during which Jason poses as a French marquis are a bit much, but the events that lead up to them, including the break from Newgate and the goings-on in the Hellfire Club, where, possibly striptease was invented, are gloriously uninhibited, and the finale has everything.
