Grease is a 1978 American musical romantic comedy film based on Jim Jacobs and Warren Casey's musical of the same name. The film depicts the life of Rydell High School students Danny Zuko and Sandy Olsson in the late 1950s. Directed by Randal Kleiser and written by Bronte Woodard, the film stars John Travolta as Danny, Olivia Newton-John as Sandy and Stockard Channing as Betty Rizzo. Grease was successful both critically and commercially. Its soundtrack album ended 1978 as the second-best selling album of the year in the United States, behind the soundtrack of Saturday Night Fever.
A sequel, Grease 2, was released in 1982, starring Maxwell Caulfield and Michelle Pfeiffer. Only a few of the original cast members reprised their roles.
