About Pat Hitchcock
Patricia Alma Hitchcock O'Connell was a British-American actress and producer. She was the only child of English director Alfred Hitchcock and film editor Alma Reville, and had small roles in several of her father's films, with her most substantial appearance being in Strangers on a Train (1951). In early 1949, her parents arrived in London to make Stage Fright, Hitchcock's first British-made feature film since emigrating to Hollywood. Hitchcock also worked for Jean Negulesco on The Mudlark (1950), which starred Irene Dunne and Alec Guinness, playing a palace maid, and again was cast as a maid in the first episode of the 1953 television series Life with Father.
