CITY OF ANGELS
In 1972, Gelbart was one of the main forces behind the creation of the television series M*A*S*H, writing the pilot (for which he received a "Developed for Television by __" credit); then producing, often writing and occasionally directing the series for its first four seasons, from 1972 to 1976. M*A*S*H earned Gelbart a Peabody Award and an Emmy for Outstanding Comedy Series and went on to considerable commercial and critical success.
Gelbart co-wrote the long-running Broadway musical farce A Funny Thing Happened on the Way to the Forum with Burt Shevelove and Stephen Sondheim in 1962. After the show received poor reviews and box-office returns during its previews in Washington, D.C., rewrites and restaging helped; it was a smash Broadway hit and ran for 964 performances. Its book won a Tony Award. A film version starring Zero Mostel and directed by Richard Lester, was released in 1966. Gelbart was critical of the movie, as most of his and Shevelove's libretto was largely rewritten.
Gelbart's other Broadway credits include the musical City of Angels, which won him the Drama Desk Award for Outstanding Book of a Musical and an Edgar Award. He also wrote the Iran-contra satire Mastergate, as well as Sly Fox and a musical adaptation of the Preston Sturges movie Hail the Conquering Hero, whose grueling development inspired Gelbart to utter what evolved into the classic quip, "If Hitler is alive, I hope he's out of town with a musical."
