'Grease' prequel is in the works and will reveal how Sandy met Danny

A "Grease prequel" called "Summer Loving" is in the works.

Deadline has confirmed that Aladdin screenwriter John August is writing a prequel to Paramount’s 1978 musical Grease.

"Summer Loving" will tell the story of how Sandy Olsson (played by Olivia Newton-John in the 1978 film) and Danny Zuko (originally played by John Travolta) first met and fell in love.

Paramount has not announced a release date or cast for "Summer Loving" as yet.

The original 1978 Grease soundtrack has sold over 38 million copies worldwide. There was a sequel to the film in 1982 starring Michelle Pfeiffer.

In 2016, Fox aired a live version of Grease starring Julianne Hough and Vanessa Hudgens which won five Emmys.
