Grease is a 1978 American musical romantic comedy film based on the musical of the same name. Written by Bronte Woodard and directed by Randal Kleiser in his theatrical feature film debut, the film depicts the lives of two high school seniors: a bad boy (played by John Travolta) and a good girl (played by Olivia Newton-John) in the late 1950s. Grease was successful both critically and commercially. Its soundtrack album ended 2003 as the second-best selling album of the year in the United States, behind the soundtrack of the 1977 blockbuster Saturday Night Fever.
A sequel, Grease 2, was released in 1982, with Maxwell Caulfield and Michelle Pfeiffer in lead roles. Few of the original cast members reprised their roles.
