The 1978 film, directed by Randal Kleiser, chronicles the senior year of the students at Rydell High, including new student Sandy (Olivia Newton-John) and leather-jacketed car aficionado Danny (John Travolta).
That year, Travolta managed the feat of being the lead in the movies that were the basis of two bestselling albums of the year, with the soundtrack for "Saturday Night Fever" coming in at No. 1 and "Grease" following behind in the second spot.
