Miller's next most notable role is that of Michael Anthony, the loyal assistant of Paul Frees' generous billionaire J. B. Tipton Jr., on the TV series The Millionaire (1955–1960). He was remembered for his recordings of Dr. Seuss stories, including Gerald McBoing-Boing, which was made into a cartoon by UPA.
