An actor with a wide range, Morgan was equally effective playing comical, befuddled men such as Jesse Kiffmeyer in Saratoga (1937) and Mr. Ferris in Casanova Brown (1944), as he was with more serious, troubled characters like Hugo Matuschek in The Shop Around the Corner (1940), Professor Roth in The Mortal Storm (1940) and Willie Grogan in The Human Comedy (1943). MGM's musical comedy film The Great Morgan (1946), is a compilation film featuring Frank Morgan supposedly as himself but playing the familiar bumbler. Occasionally a co-star (as in The Human Comedy, and, once established, invariably a featured player), he also saw the occasional lead deep in his Hollywood career, as the philanthropic tycoon falsely accused of murder in 1941's Washington Melodrama and The Great Morgan (in which he is the Morgan of the title, the picture's central player).
