Sandy was a zombie? Olivia Newton-John's 'Grease' theory will give you chills

/ Source: TODAY

Remember the "Grease" theory that resurfaced in September, in which we're meant to believe that Sandy (and possibly Danny) were dead or dying all along?

Olivia Newton-John, who played Sandy in the classic 1978 movie, has now waded into the discussion and it sounds like she comes up on the side of ... Undead Sandy!

"There was some theory that (Sandy) really died in the beginning, and at the end we were going back to heaven," she told TODAY on Tuesday. "Something crazy and hilarious ... But I thought, 'That means we were the first zombie movie ever and we looked pretty good for zombies.' Don't you reckon?"

OK, that's clearly not true (films about the undead date back to at least the 1930s), but arguably "Grease" would have been the first musical zombie movie.

In any case, Newton-John's take adds another layer to what the "real" story might be. The theory that first surfaced on Reddit in 2013 but got new life when Sarah Michelle Gellar posted about it in September, posited that "the entire movie was a drowning woman's coma fantasy." Seeing Sandy and Danny drive up into the heavens in a restored Greased Lightning car at the end of the film seemed to give the idea credibility.

But so far, no confirmation. The closest TODAY got was from an email sent by "Grease" director Randal Kleiser, who wrote, "I've read all the comments and theories about the ending of 'Grease.' I am in the midst of writing a book and will reveal all about that."
