Grease is a 1978 American musical film directed by Randal Kleiser and based on Jim Jacobs' and Warren Casey's musical, of the same name about two star-cross'd lovers in a semi-modern-day 1959 high school. The film stars John Travolta, Olivia Newton-John, Stockard Channing, and Jeff Conaway.
Although referring to the early 1950s, it was successful both critically and at the box office, consolidating Travolta's career at that time and bringing Newton-John to a wider audience.
Its soundtrack album became one of the best-selling in pop movie history, and provided several chart hits and not only for the original artists.
