After a career as a singer, Hoey moved to acting on the stage in 1918 and later to films. In 1931, he moved to the United States and began appearing in Hollywood films. He also played Mr. Rochester opposite Katharine Hepburn in the American production of Helen Jerome's stage adaptation of Jane Eyre.
