Jimmy Savo one of the most popular and high-salaried Comedians in Vaudeville, is the bright Comedy Star of "Carry on, Sergeant!" Like all great Comedians, his power over pathos is as great as his power to make you laugh. He has full scope as Syd. Small, and Jimmy makes the most of the part, both in laughter and tears. Niles Welch who plays the part of Donald Cameron, handles this most important role with all the understanding and restraint that is needed. His long screen experience and the sureness of his artistic work bring about a fine performance and a realistic character portrayal.
