Fresh from Hammer's Taste of Fear, Ronald Lewis teamed up with William Castle for what the famed horror producer considered one his favourite films. Lewis plays Sir Robert Cargrave, a British doctor who receives a letter from an ex-lover about an intriguing case. Her husband, the titular Mr Sardonicus (Guy Rolfe, Yesterday's Enemy), requires medical attention for his horribly deformed face... Once seen, you'll never be able to forget it.ExtrasHigh Definition remasterOriginal mono audioAudio commentary with film historians Samm Deighan and Kat EllingerGothic Castle (2018, 28 mins): critical analysis by Jonathan Rigby, author of American Gothic: Six Decades of Classic Horror CinemaThe Punishment Poll (2018, 6 mins): interview with publicist Richard KahnTaking the Punishment Poll (2002, 8 mins): archivist Bob Burns and filmmakers David Del Valle, Michael Schlesinger and Fred Olen Ray discuss the filmIsolated music & effects trackOriginal theatrical trailerStuart Gordon trailer commentary
