In 1955, Warren wrote "The Legend of Wyatt Earp", which was used in the ABC/Desilu Studios television series, "The Life and Legend of Wyatt Earp". He also wrote the opening theme, "Hey, Marty" (lyrics by Paddy Chayefsky), for the film "Marty", which won the Academy Award for Best Picture in 1955. The last musical score that Warren composed specifically for Broadway was "Shangri-La", a disastrous 1956 adaptation of James Hilton's "Lost Horizon", which ran for only 21 performances. In 1957, he received his last Academy Award nomination for "An Affair To Remember". He continued to write songs for movies throughout the 1960s and 1970s but never again achieved the fame that he had enjoyed earlier. His last movie score was for "Manhattan Melody", in 1980, but the film was never produced.
