Alfred Hitchcock

Alfred Hitchcock was already Britain's leading director, with The 39 Steps and The Lady Vanishes, when producer David O. Selznick brought him to Hollywood in 1939. Rebecca won the best picture Oscar the following year, and the American studio system's resources made possible Rear Window, Vertigo and Psycho. He became a US citizen in 1955, though he kept his London accent and cockney humour.
