Opposite the Sam Spade of Ricardo Cortez in The Maltese Falcon (1931), Warner Bros.' 1931 adaptation of Dashiell Hammett's novel, Digges portrayed "Kasper Guttman" - the role wonderfully reprised in Warners' 1941 version (The Maltese Falcon (1941)) by Sydney Greenstreet.
Though his on-screen persona never seemed to vary much from that of, say, Ebenezer Scrooge, he was a very well-respected stage actor and director, with a particular fondness for the works of Henrik Ibsen. Digges enjoyed an enormously successful career as a Broadway actor and director (active there from 1906-47) in addition to his work as a character actor in Hollywood.
