Robert Lopez and Kristen Anderson-Lopez had a hit on their hands with "Frozen," and now the duo is making their next move.

"Up Here" is the next title they are working on. It's a stage musical that will be a part of the 2015-2016 season at La Jolla Playhouse. The musical will be a romantic comedy, which is right up Lopez's alley. He was a co-writer for "The Book of Mormon" and helped write puppet show "Avenue Q."

"It is witty, it is wicked smart, it is irreverent," said Scott Sanders, the show's producer. "It will appeal to a broad audience but it certainly will be something that even Millennials will relate to."

Lopez and his wife Anderson-Lopez wrote the songs for Frozen, and they won the Best Original Song Oscar for "Let It Go."

Anderson-Lopez is a producer for the Disney World show "Finding Nemo."

"I've been fans of the Lopezes for a very long time," Sanders said.

The show will be directed by Alex Timbers.

"Some of the characters are written in one of the protagonists's imagination and it's going to allow for some creative staging -- so, of course, nobody's better at that than Alex Timbers," Sanders added.

Lopez and Anderson-Lopez have written the songs, lyrics and story for the new musical.

This is how La Jolla describes the new musical: "Dan is an ordinary guy with a boring social life, an unused gym membership and a lot going on upstairs. When he finds a potential spark with Lindsay, his attempts at love are jeopardized by his chaotic subconscious mind. Academy Award-winning composers Robert Lopez and Kristen Anderson-Lopez team up with acclaimed writer/director Alex Timbers to create this new musical comedy about moving past ourselves -- and those little voices in our head -- to find happiness."
