Grease is still the word

The story behind the classic movie musical. The programme examines the original stage musical in the early 1970s, which starred a young Richard Gere, and the changes that occurred between stage and screen, including the addition of several new songs and toning down the original show's darker elements. Plus, a look at some of the actors who could have played the roles made famous by John Travolta and Olivia Newton-John.
