Radio comedy writer who initially penned schtick for Milton Berle, Danny Thomas and Bert Lahr until his breakthrough, the creation of the radio series "My Friend Irma" (1947). In 1949, Howard scripted the film version of "My Friend Irma", featuring the film debut of the celebrated comedy team, (Dean) Martin and (Jerry) Lewis. He went on to write the sequel, "My Friend Irma Goes West" (1950), and the comic duo's fourth feature, "That's My Boy" (1951), which he also associate produced. In 1952, "My Friend Irma" became a TV series, running on CBS for two seasons. Howard joined Desilu Studios in 1959, working for five years under a production and development deal.
Howard returned to screenwriting with the Frank Sinatra and Dean Martin vehicle, "Marriage on the Rocks" (1965) before making his feature directorial debut with the outstanding ensemble comedy "Lovers and Other Strangers" (1970). The film and its director garnered praise for the skillful way it utilized its sharp comic screenplay and the credible and funny performances of Bea Arthur, Richard Castellano, and many others. A subsequent directorial effort, "Every Little Crook and Nanny" (1972), offered a clever premise but was not especially well received. Howard subsequently focused on his writing, which included the screenplay for "Won Ton Ton, the Dog Who Saved Hollywood" (1976). Divorced from actresses Nan Wynn and Gloria Grahame, Howard was married to studio mogul Jack Warner's daughter Barbara.
