Grease

One of Broadway's biggest ever hits became Hollywood's blockbuster of the year and the most successful movie musical.

Evoking nostalgia for 1950s America, it is the tale of teenage love and school cliques with John Travolta and Olivia Newton-John. Danny's a 'T-Bird' but Sandy is too pure and good to be a 'Pink Lady' and feels she has to become cool in order to win Danny back.
