Years before he played The Wizard (and four other roles) in The Wizard of Oz (1939), Frank Morgan had a long career in silent film and was nominated for a Best Actor Oscar for The Affairs of Cellini (1934). Although adept at flustered and bewildered comic roles, Morgan was also an excellent dramatic actor; he was an ever-present figure in many of MGM's classiest films of the period. Highlights of his career include: Hallelujah, I'm a Bum (1931), When Ladies Meet (1933), Bombshell (1933), Cat and the Fiddle (1934), The Good Fairy (1935), Naughty Marietta (1935), Dimples (1936), The Last of Mrs. Cheyney (1937), Saratoga (1937), Rosalie (1937), Boom Town (1940), Broadway Melody of 1940 (1940), and The Three Musketeers (1948). He was especially effective in The Shop Around the Corner (1940), The Mortal Storm (1940), The Human Comedy (1943) and Summer Holiday (1948), the musical remake of Thornton Wilder's Ah, Wilderness. Morgan died while filming Annie Get Your Gun, in which he would have played Buffalo Bill. The most famous anecdote about Morgan is that while rehearsing for The Wizard of Oz, he went looking for a coat to help him feel like Prof. Marvel; the one he found in a second-hand shop turned out to have originally belonged to Wizard author L. Frank Baum.
