John Travolta, Olivia Newton-John, Stockard Channing, Jeff Conaway, Didi Conn
Transferring its setting from Chicago to sunny California, and adding a dash of disco to the 1950s score, producer Allan Carr and director Randal Kleiser turned this long-running Broadway smash into the biggest blockbuster of 1978. Teens Danny (John Travolta) and Sandy (Olivia Newton-John) spend their summer nights falling in love, but once fall comes, it's back to Rydell High and its cliques. As one of the bad-boy T-Birds, Danny has to act cool for best pal and their leather-clad mates. Despite befriending Frenchy, one of the rebel Pink Ladies, virginal Sandy is too pure to join their group. Declaring their devotion in ballads, Sandy and Danny split, reconcile, and split again amidst a pep rally, dances, drive-ins, and a drag race, before deciding "You're the One That I Want" at the carnival.
