Chamber of Horrors (1966), directed by Hy Averback, brings a compelling cast and an intriguing plot to the table, promising much with its premise but ultimately delivering a middling experience. The story revolves around a deranged murderer, Jason Cravette (played by Patrick O’Neal), who, after escaping execution, embarks on a grisly path of revenge. Adding to the intrigue, Cravette’s severed hand is replaced with various weapon attachments, turning him into a unique, albeit underutilised, antagonist in this Gothic-inspired tale.

The ensemble cast is a highlight. Wilfrid Hyde-White and Cesare Danova bring charm and wit as the amateur sleuths operating out of a wax museum who try to solve the gruesome crimes. Laura Devon as Marie Champlain adds an element of romantic allure, while O’Neal does his best with Cravette, crafting a chilling performance as a vengeful madman with a penchant for leaving his victims in creatively staged scenarios. Their combined talents elevate the film, giving it moments that shine despite the otherwise flat storytelling.

The plot, though clever in its concept, quickly falls into formulaic territory, relying heavily on gimmicks like the “Fear Flasher” and “Horror Horn”—signaling moments when audiences should brace themselves for terror. These devices, while initially engaging, fail to sustain the suspense, resulting in a series of anticlimactic sequences that detract from the film’s tension. The movie’s energy sags under the weight of predictable scenes that feel less terrifying and more theatrical, ultimately failing to evoke the intended horror.

Though it has a visual flair, with its dark, misty atmosphere and elaborate period costumes, Chamber of Horrors misses the mark in pacing. The film feels padded, and the lack of genuine thrills or surprises makes it feel more like a TV special extended to a feature-length runtime. The concept of a wax museum as a horror setting is ripe with potential, yet the film never fully capitalises on the sinister possibilities, choosing instead to tread familiar ground that fails to grip the audience.

Chamber of Horrors is far from a total misfire, as it does offer a macabre curiosity for fans of 1960s horror with its eccentric villain and a cast that brings spirit to the lacklustre script. But for all its tricks and stylistic flourishes, it’s a film that, in the end, feels like a missed opportunity—one that hints at terror but struggles to sustain it, leaving audiences with a chamber that’s more dreary than dreadful.
