Grease is a 1978 American musical romantic comedy film directed by Randal Kleiser and produced by Paramount Pictures. It is based on Warren Casey and Jim Jacobs' 1971 musical of the same name about two lovers in a 1950s high school. The film stars John Travolta, Olivia Newton-John, Stockard Channing, and Jeff Conaway. It was successful both critically and at the box office. 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, another film starring Travolta.
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.
