Already a runaway success on the American stage, the screen version of retro-musical 'Grease' made it a hit around the globe, cemented John Travolta's star status, and ensured the show's revival in numerous incarnations up until the present day. After their summer romance ends, Danny (Travolta) and Sandy (Olivia Newton-John) are unexpectedly reunited at high school when the latter moves to Danny's town. However, their relationship stalls when it becomes apparent that Sandy is not 'cool' enough to date gang leader Danny. Hit songs include 'You're the One That I Want' and 'Greased Lightning'.
