Peter O'Toole later played Sherlock Holmes' creator Arthur Conan Doyle in FairyTale: A True Story (1997).
Peter O'Toole's voice performance as Sherlock Holmes was not his first connection to the role. He was Billy Wilder's first choice for the Victorian sleuth in " The Private Life of Sherlock Holmes ", and he was also sought to play the Baker Street detective in the 1979 " Murder by Decree " where he would have had Laurence Olivier by his side as Watson.
