Sully was often cast as a heavy or villain throughout his career. Modern viewers will recognize Sully in his appearances in several late Three Stooges films such as Fling in the Ring, Pardon My Backfire and Guns a Poppin. In comedy, perhaps his most memorable role was as the bewildered waiter who thinks he is seeing triple in the Stooges' A Merry Mix Up. Dramatically, Sully is remembered as one of the Joad family members 'Noah Joad', whose family treks across country for a new life, in the 1940 classic John Ford film The Grapes of Wrath.
