in the final film. MacArthur made his Broadway debut in 1960, playing opposite Jane Fonda in Invitation to a March, for which he received a Theatre World Award. Although he never returned to Broadway, he would remain active in theatre throughout his career, appearing in such productions as Under the Yum Yum Tree, The Moon Is Blue, John Loves Mary (with his then-wife Joyce Bulifant), Barefoot in the Park, and Murder at the Howard Johnson's. He also released several records in the early 1960s, scoring two minor hits with "(The Story of) The In-Between Years" and "The Ten Commandments of Love," both of which peaked at number 94 in the Billboard Hot 100. MacArthur gave a particularly chilling performance as baby-faced opium dealer Johnny Lubin in The Untouchables episode, "Death For Sale." He was in Bus Stop and Wagon Train. He returned to features as one of several young actors in The Interns (1962), Columbia's popular medical drama. He did episodes of The Dick Powell Theatre, Sam Benedict, and Arrest and Trial, then made Spencer's Mountain (1963) at Warner Bros. with Henry Fonda and Cry of Battle (1963) in Philippines. In 1963, he was nominated for the "Top New Male Personality" category of the Golden Laurel Awards 1963. That year he starred in and produced a pilot for a series about a writer, Postmark: Jim Fletcher, but it was not picked up. He guest starred in Burke's Law, The Eleventh Hour, and The Great Adventure. After an episode of The Alfred Hitchcock Hour he did The Truth About Spring and The Bedford Incident, both in 1965. His role in The Bedford Incident was of a young ensign who became so rattled by the needling of his captain (Richard Widmark), that he accidentally fired an ASROC at a Soviet submarine, thus creating a nuclear incident when the submarine returned fire, resulting in the destruction of both vessels. In Battle of the Bulge (1965), he again played the role of a young and inexperienced officer. MacArthur was in Ride Beyond Vengeance (1966) and guest starred in Branded, Combat!, Gunsmoke, Hondo, Insight, Death Valley Days, Bonanza, and The Virginian. In 1966, he guest-starred as Lt. Harley Wilson in "The Outsider," episode 20 in the second season of Twelve O'Clock High. He co-starred with his mother in the 1968 episode "The Pride of the Lioness" on the Tarzan television series.
