Travolta dishes on Sandy ‘death clues’ in ‘Grease’

John Travolta is a big fan of that “Grease” internet theory that went viral — that co-star Olivia NewtonJohn’s Sandy is actually dead in the film.

Morbid, yes. But worldwide debate around the premise proves how powerfully the 1978 classic musical, which starred Travolta as greaser Danny, resonates as it turns 40 on June 16.

“I love it, imaginations are awesome,” Travolta, 64, said recently on a call from France, where he celebrated the movie’s anniversary with a screening at the Cannes Film Festival. (The movie is out on Blu-ray in a newly restored edition.)

“These things are bound to happen to something timeless like this. It’s so fun.”

Travolta was fascinated when the theory went viral in 2016. It speculated that Sandy drowned while frolicking with Danny on the beach at the start of the movie — and the entire story is her coma fantasy.

This would explain Danny’s boast to his male friends, “I saved her life; she nearly drowned” on the song “Summer Nights.” And the happy duo flying their convertible into the clouds for the famous ending signified Sandy ultimately dying.

Does the theory work for Travolta? “I could have fun with it,” he said. “But I know the writers of ‘Grease,’ and I was around in the original days. I can’t take it too far.”

Danny is exaggerating when he says he saved Sandy’s life, Travolta pointed out.

“He’s bragging, it was made up to impress the boys,” he said. “(Sandy and Danny) have two different stories and somebody is lying. Most likely, it’s Danny. But I don’t want to spoil the fun for everyone,” he added.

The actor believes that, somewhere, Sandy and Danny are still together: “Sandy and Danny were the real deal.”

Director Randal Kleiser has kept silent on the theory, promising to reveal his answer at length in a planned book.
