Roderick Andrew Anthony Jude McDowall was a British-American actor, whose career spanned over 270 screen and stage roles across over 60 years. Born in London, he began his acting career as a child in his native England, before moving to the United States at the outbreak of World War II. He achieved prominence for his starring roles in How Green Was My Valley (1941), My Friend Flicka (1943), and Lassie Come Home (1943). Unlike many of his contemporaries, McDowall managed to transition his child stardom into adulthood, and began to appear on Broadway as well as in films, winning a Tony Award for his performance in Jean Anouilh's The Fighting Cock. For portraying Octavian in the historical epic Cleopatra (1963), he was nominated for a Golden Globe Award.

How Green Was My Valley is a 1941 American drama film directed by John Ford, adapted by Philip Dunne from the 1939 novel of the same title by Richard Llewellyn. It stars Walter Pidgeon, Maureen O'Hara, Anna Lee, Donald Crisp, and a young Roddy McDowall.
