After making his first U.S. appearance in 1913, Rains returned to England, served in the Scottish regiment during WWI, then established himself as a leading actor in the postwar years. He was also featured in one obscure British silent film, Build Thy House. During the 1920s, Rains was a member of the teaching staff at the Royal Academy of Dramatic Art; among his pupils were a young sprout named Laurence Olivier and a lovely lass named Isabel Jeans, who became the first of Rains' six wives. While performing with the Theatre Guild in New York in 1932, Rains filmed a screen test for Universal Pictures. On the basis of his voice alone, the actor was engaged by Universal director James Whale to make his talking-picture debut in the title role of The Invisible Man (1933).
