Cinema showman William Castle's best films are imbued with an infectious sense of mischief that overcomes deficiencies, and House on Haunted Hill is no exception. An excellent vehicle for star Vincent Price and one of Castle's most beloved concoctions, this lightweight ghost story is lots of fun even without the director's trademark theater gimmicks. Price is in prime form, alternating between pure ham and quiet subtlety, able to express a macabre notion simply by arching an eyebrow. Co-star Elisha Cook Jr. has only one task here, to look shell-shocked and mutter predictions of doom, and he performs it with twitchy, sweaty aplomb. The rest of the cast is serviceable, with only ingenue Carolyn Craig standing out via her shrill shrieks and stilted line readings. Castle directs House on Haunted Hill to be spooky rather than frightening, with floating skeletons and flickering candlelight, but a few ghastly images of acid baths and hanged women slide in for the E.C. Comics crowd. Campy and creepy in equal measures, House on Haunted Hill deserves its status as a horror classic.
