Grease's director breaks down the 'You're The One That I Want' scene

Grease was the first feature Randal Kleiser ever directed. That was 1978. Forty years later, Kleiser breaks down the now-iconic "You're The One That I Want" scene, the "electrifying" musical number where the "Bad Sandy" shows up. Did you know that Olivia Newton-John was sewn into those tight zippered pants and was stuck in them all day? Talk about suffering for your art.

A special 40th anniversary edition of Grease is now available.
