Q: Passage: Whale was born into a large family in Dudley, Worcestershire. He discovered his artistic talent early on and studied art. With the outbreak of World War I he enlisted in the British Army and became an officer. He was captured by the Germans and during his time as a prisoner of war he realized he was interested in drama. Following his release at the end of the war he became an actor, set designer and director. His success directing the 1928 play Journey's End led to his move to the US, first to direct the play on Broadway and then to Hollywood, California, to direct films. He lived in Hollywood for the rest of his life, most of that time with his longtime companion, producer David Lewis. Apart from Journey's End (1930), which was released by Tiffany Films, and Hell's Angels (1930), released by United Artists, he directed a dozen films for Universal Pictures between 1931 and 1937, developing a style characterized by the influence of German Expressionism and a highly mobile camera.
