Dunn "wasn't playing the role with enough gentlemanliness". The director defended Dunn's interpretation of the script. Meanwhile, Dunn felt out of his league playing tragedy rather than comedy. He had never seen an O'Neill play and said his wife had persuaded him to take the part for the "prestige". The production budget was increased by 10% to enable dress rehearsals to take place in New York rather than in the first out-of-town tryout in Columbus, Ohio, in order to accommodate Dunn's poor health. While Dunn's performance garnered critical praise on the tour, he left the production before it reached Broadway. In 1948, Dunn succeeded James Stewart in Harvey, appearing in 108 performances of the long-running Broadway play. In 1951, Dunn played Willy Loman in Death of a Salesman at the Norwich Summer Theater. In 1964, he played the title role in Finian's Rainbow in a 2-week summer engagement at the Melodyland Theatre in Anaheim, California. Television career In 1949, Dunn pursued a new direction as a character actor on television. He guest-starred in dozens of episodes of popular television series in the 1950s through mid-1960s, including Bonanza, Rawhide, Route 66, Ben Casey, and The Virginian.

The three male comedians had good rapport and often ad-libbed their lines. The role required Dunn to play slapstick, which he had only done previously on stage. In 1962, Dunn played a clown in full makeup and costume in an episode of Follow the Sun, and sang "On the Good Ship Lollipop" from his 1934 film Bright Eyes. In 1963 he played the character of P. J. Cunningham, the manager-driver for a music band led by Bobby Rydell, in the unsold Desilu half-hour television pilot Swingin' Together. Screen persona and recognition Dunn's smile, described as "sunny", "whimsical", "infectious", and "winning", was often singled out as an asset. The Arcadia Tribune claimed Dunn's smile was "patterned after the one the Prince of Wales uses". In his Hollywood heyday in the 1930s, Dunn was noted for his "clean-cut good looks and boyish charm". As he matured, The New York Times described Dunn's
