In the mid-16th century, Englishman Francis Barnard (John Kerr) travels to the Spanish castle of Nicholas Medina (Vincent Price) to try and uncover the details surrounding the sudden death of his sister Elizabeth (Barbara Steele), Nicholas's wife. Soon after arriving at the castle, Francis begins to suspect that Nicholas is hiding the truth, but what he eventually discovers is far more terrible than he could have imagined.
I'm not the greatest fan of the Roger Corman/Edgar Allen Poe cycle of films, finding their combination of creaky Gothic trappings, trite atmospherics and overwrought melodrama just a little too cheesy to be wholly effective; for much of the time, Pit and the Pendulum is just the same, with Price hamming it up and Corman laying on the eeriness with a trowel.
Thankfully, the film is short enough to prevent boredom kicking in and is saved somewhat by a great final act that provides one or two neat twists, some well handled excitement (the razor-sharp pendulum of the title finally making an appearance, swinging to and fro above a shackled Francis) and a befitting closing shot (I won't say what it is, but it's a corker).
