Grease: Then and Now

Julianne Hough and Aaron Tveit will take the stage as Sandy and Danny in Fox's production of Grease: Live on Sunday. The two performers step into the famed shoes previously worn by Olivia Newton-John and John Travolta in the 1978 big-screen adaptation of Warren Casey and Jim Jacobs' musical. In honor of Grease: Live, see the stars with those that came before them, ahead.
