Vincent Price plays a washed-up B-movie star who may have a problem getting out of character when his celebrated alter ego, Doctor Death, apparently commits a string of murders influenced by his own back catalogue. An enjoyable, undemanding though silly horror film whose appeal chiefly rests in the all-too-rare opportunity to see Price acting opposite Peter Cushing, rarer still as the latter has a habit here of disappearing for long stretches at a time, so much so that one can only assume that he was only available to the production for a couple of days. With a cast that includes not only Cushing but also Adrienne Corri and Linda Hayden, you'd be forgiven for thinking that Hammer had a hand in the film, but it's actually a co-production of American International Pictures and Amicus, Hammer's American equivalent and its main British rival at the time. There's a lot of recycling of AIP highlights from the Sixties, allowing for second-hand screen credits for Karloff and Rathbone, so it's perhaps not surprising that an excellent editor, Jim Clark, was chosen to direct. As far as I'm aware, this was Clark's last outing as a director, after which he returned to editing. His impressive credits in that capacity include The Innocents, Charade, Marathon Man, The Killing Fields, The Mission and Vera Drake.
