Grease (1978)

This film adaptation of GREASE is the zippy smash hit translation from the Broadway musical tribute to the fabulous 1950s. As a new school year begins, wholesome Australian exchange student Sandy (pop star Olivia Newton-John) and duck-tailed, leather-jacket-clad Danny (John Travolta) parlay their summertime romance into an on-and-off attraction that may or may not cross clique lines.
