Thirty years on, toes still tap to the fabulous Bee Gees score of this sweet-and-sour story of life in the slums of Brooklyn.

As hardware store worker and disco dancing king Tony, snake-hipped John Travolta powered his way to stardom with a Best Actor Oscar nomination.

The film's SO Seventies - who could resist that disco beat and, boy, could Travolta dance! To prepare for the role, he ran two miles and danced for three hours daily, losing 20lb in the process.
