In 1977, Stigwood asked him to produce the ad campaign for "Saturday Night Fever," and he turned the film's premiere into a star-studded television special. It worked so well that Stigwood gave him "Grease" (1978). Carr not only helmed the ad campaign and produced the premiere party and television special for "Grease", but also co-produced the film for six million dollars, casting his then client Olivia Newton-John. It became the highest-grossing film of the year, and one of the highest-grossing films up until that time, at just under $100 million. The film was nominated for five Golden Globe Awards and won two People's Choice Awards, for Best Picture and Best Musical Picture. That year he even appeared in a role on the final season of the Angie Dickinson television series "Police Woman". Stigwood and Carr would work on several other films, including 1978 Oscar-winning "The Deer Hunter".
