In 1958, producer Richard Gordon offered Boris Karloff a two-picture deal with director Robert Day. The dual productions, The Haunted Strangler and Corridors of Blood, would be A (or A-) budget productions, providing the actor a starring role and a salary to match. Karloff jumped at the offer. It had been twelve years since his last star-quality vehicle, the Val Lewton-produced Bedlam (directed by Mark Robson). Since then, Karloff had been stuck in character parts (1951’s The Strange Door, 1952’s The Black Castle), playing opposite Abbott and Costello (1949’s Abbott and Costello Meet the Killer), or crap (1954’s The Island Monster and 1957’s Voodoo Island). He had fared better in television (as one of the few big screen stars of the time who had no qualms jumping to the small screen).
The Haunted Strangler is often assessed as the lesser of the two Day/Karloff films, with the actor at his hammiest since 1934’s The Lost Patrol (directed by John Ford and featuring Karloff’s worst performance). Much of the film’s considerable budget went into expensive sets and into securing its lead actor, which unfortunately short-shifted the makeup department: Karloff’s Hyde-like transformation is reduced to the actor tilting his head, mussing up hair, twisting his hand into a claw, and biting lower lip. It is distracting as hell, and critics have been divided on assessing his performance as a whole. Another oft-cited critique is the predictable storyline. In its defense, classic horror fans usually rely on the overused virtues of atmosphere. There are also lurid elements of exploitation (champagne-soaked cleavage, Busby Berkeley-inspired can-can crotch shots, gruesome murders of women, floggings, bedlam abuses, broken glass to the face, etc) to keep up the interest.
