The Devil Rides Out was restored by StudioCanal and released on Blu-ray in 2012. Based on Dennis Wheatley's famous novel, the film is considered to be one of Hammer studios the finest works, made at the height of their success. The story centres around a group of friends who meet for a reunion, only to discover that one of their circle has fallen into the clutches of a satanic cult. The Duc de Richleau (Christopher Lee) and Rex Van Ryn (Leone Greene) soon find themselves up against cult leader Mocata (Charles Grey), who is not disposed toward releasing his new acolyte Simon Aron (Patrick Mower). The Devil Rides Out features an intelligent screenplay by Richard Matheson and strong performances by Christopher Lee and Charles Gray. As ever with Hammer movies, the production designed is polished and looks more lavish than it is. Unfortunately, the films poor box office returns outside of the UK, meant that the studio declined to make any further adventures of the Duc de Richleau.
