Who played Danny in the movie "Grease"?

John Travolta played Danny in the movie "Grease." In the 1978 musical film, he portrays Danny Zuko, the leather-jacketed leader of the T-Birds at Rydell High School.

Danny's central storyline involves Sandy Olsson, played by Olivia Newton-John. The pair fall in love during a summer romance, then unexpectedly reunite when Sandy transfers to Danny's high school. Their relationship drives several of the film's best-known musical numbers, including "Summer Nights," "Sandy," and "You're the One That I Want."

Grease was directed by Randal Kleiser and adapted from the stage musical by Jim Jacobs and Warren Casey. Travolta's performance helped establish him as a major film star after his success in Saturday Night Fever. A common mix-up is confusing Danny with Kenickie, played by Jeff Conaway, another prominent member of the T-Birds. The film became the highest-grossing movie of 1978 and remains one of the most recognizable screen musicals.
