|All 3 actors were often cast in similar roles. I agree that Moore was particularly memorable in Make Way for Tomorrow and It Happened on Fifth Avenue. He also had small roles in such musical films as Swing Time, Louisiana Purchase, This Is the Army, Ziegfeld Follies, and countless other movies.
Henry Travers and Harry Davenport were fine dramatic actors and both had prolific careers in movies. Travers is remembered for Death Takes a Holiday, Mrs. Miniver, Shadow of a Doubt, The Moon Is Down, It's a Wonderful Life, The Bells of St. Mary's, and so many others.
Harry Davenport was unforgettable in The Life of Emile Zola, Gone With the Wind, The Hunchback of Notre Dame, Meet Me in St, Louis, Juarez, The Ox-Bow Incident, and the list goes on.
Moore, Travers, and Davenport all had extensive careers on Broadway, with Moore and Travers occasionally creating roles on stage and then appearing in the film versions either repeating those roles or cast as different characters.
