It feels like I’ve faded away, and maybe everyone else has too. Jim Clark directed Madhouse, with the script by Angus Hall, Ken Levison, and Greg Morrison. The cast includes Vincent Price, Peter Cushing, Robert Quarry, Adrienne Corri, and Natasha Pyne; Douglas Gamley composed the music, and Ray Parslow was in charge of cinematography. The film centers on a horror icon who returns to his well-known role after dealing with a mental health crisis. However, it appears that the character is responsible for actual murders happening in real life. The “madhouse” mentioned in the title serves as a symbolic representation of the movie business itself, and the filmmakers include some subtle comments about the industry that supported them, though some of these jokes are quite clever. Featuring celebrated horror actors Price, known from "AIP" films, and Cushing, associated with "Hammer," it’s more like an affectionate tribute to the genre than a truly significant work—particularly because the two stars don't share enough screen time together. The movie is full of misleading clues and some scenes just don’t quite add up; at times, you get the sense that the story was developed quickly. Including snippets from a few Corman films starring Price, along with other nods to classic horror, are welcome additions, but ultimately it feels like an idea thrown together, borrowing elements from the "Dr. Phibes" formula. The ending reveal isn't particularly impressive or unexpected either. It’s not a fantastic film (it remained unreleased for two years), but there’s still plenty to appreciate—like Corri’s eccentric character who is obsessed with spiders, Michael Parkinson’s interview with Price, and even Price singing! Ultimately, it’s best enjoyed by fans of Vincent Price because his horror career was nearing its end. 6/10
