His most significant works include appearances in high-profile films such as the western *Destry Rides Again* (1939), alongside James Stewart; the war film *Flying Tigers* (1942), with John Wayne; and especially the celebrated film noir *Detour* (1945), where his character is crucial to the plot's development.
