When his career took him to London in 1954 after his provincial apprenticeship, his agent informed him that there was already a Michael White performing as an actor in London and that he had to come up with a new name immediately. Speaking to his agent from a telephone booth in Leicester Square, London, he looked around for inspiration, noted that The Caine Mutiny was being shown at the Odeon Cinema in 1954, and decided to change his name to "Michael Caine". He joked on television in 1987 that, had a tree partly blocking his view been a few feet to the left, he might have been called "Michael Mutiny". (Humphrey Bogart was his "screen idol" and he would later play the part originally intended for Bogart in John Huston's The Man Who Would Be King. ) He also later joked in interviews that had he looked the other way, he would have ended up as "Michael One Hundred and One Dalmatians". In 1959, he was Peter O'Toole's understudy in Lindsay Anderson's West End staging of Willis Hall's The Long and the Short and the Tall. He took over the role when O'Toole left to make Lawrence of Arabia and went on to a four-month tour of Britain and Ireland.
