It centers around the idea that her character, Sandy, was dead the entire movie. Yes, according to the theory, Sandy drowned (cue the song "Summer Nights") and the whole plot was a fantasy.

Far-fetched? Yes. Completely crazy? No.
"Well, I laughed," she said. "I thought it was hilarious. I thought it was wonderful that people were still talking about it all these years later. Then I thought, if that's the case, we were the first zombie musical, and we look pretty good considering!"

"It's been incredible. When I do my shows, there are little kids who are coming with their grandparents and they've just discovered the movie and it's lovely. It's great to know that you're giving people pleasure like that and that they love the songs. The songs are fantastic," she said.
Meanwhile, Newton-John is about to release "Liv On," a new album she recorded with singer-songwriters Beth Nielsen Chapman and Amy Sky that centers around themes of grief, loss and hope.
