From Wikipedia, the free encyclopedia. Thorley Walters (born 12 May 1913, Teigngrace, Devon – 6 July 1991, London) was an English character actor. He is probably best remembered for his comedy film roles such as in Two-Way Stretch and Carlton-Browne of the FO. He also appeared in the acclaimed TV drama Tinker, Tailor, Soldier, Spy. Walters played Sherlock Holmes sidekick Doctor Watson in four unrelated films: Sherlock Holmes and the Deadly Necklace (1962), The Best House in London (1969), The Adventure of Sherlock Holmes Smarter Brother (1975), and Silver Blaze (1977). He featured in three of the St Trinians movies, starting as an army major in Blue Murder at St Trinians. He later appeared as Butters, assistant to Education Ministry senior civil servant Culpepper-Brown (Eric Barker) in The Pure Hell of St Trinians and played the part of Culpepper-Brown in The Wildcats of St Trinians. In the 1960s he also appeared in several Hammer horror films, including The Phantom of the Opera (1962), Dracula, Prince of Darkness (1966), Frankenstein Created Woman (1967) and Frankenstein Must Be Destroyed (1969). In the DVD commentary to The Man Who Haunted Himself, Roger Moore mentioned that co-star Walters lived in Dolphin Square, the prestigious apartment block in Pimlico, London in which some scenes of the film were shot. Thorley and Richard Hope-Hawkins visited the ailing Terry-Thomas in Barnes, London in 1989. Walters had starred with Terry in the Boulting Brothers film Carlton-Browne of the F.O.
