"Grease," based on the hit 1972 Broadway musical of the same name, follows Danny, a local bad boy, and Sandy (Olivia Newton-John), a wholesome high school transfer student from Australia, as they reunite at Rydell High School after meeting at the beach over the summer.

Fans at the 'Grease' Sing-A-Long screening at the Hollywood Bowl last night got a surprise when the original Danny Zuko strutted out onstage.

Released in 1978, Travolta starred in “Grease” alongside Olivia Newton-John, who died in 2022. Other cast members include Stockard Channing, Jeff Conaway, Jamie Donnelly, Dinah Manoff and Eve Arden. Made for only $6 million, the film became Paramount’s highest earner by the end of its run, with a gross of more than $130 million.
