The dancing queens are getting ready to sing again.

Universal is moving on a sequel to Mamma Mia, the 2008 adaptation of the stage musical based on ABBA songs that was one of the biggest hits in studio history, grossing $609 million worldwide.

Ol Parker, the writer of The Best Exotic Marigold Hotel and its sequel, has been tapped to direct what is being titled Mamma Mia: Here We Go Again, with the new musical being slotted for a release on July 20, 2018.

Much of the original movie’s cast, which included Meryl Streep, Pierce Brosnan, and Colin Firth, are expected to return to sing more ABBA songs.

The storyline, according to sources, is both a prequel and a sequel. It will be set in the present with the returning castmembers, while new actors would play younger versions of Streep, Brosnan, and Firth for part of the story that is set in the past.

Also returning are the producers: Playtone’s Gary Goetzman and Littlestar’s Judy Craymer, who is the creator and producer of the long-running stage musical.

Parker previously directed Now Is Good, a weepie that starred Dakota Fanning. (He’s also Thandie Newton’s husband.) He is repped by the UK’s Knight Hall and Management 360.
