Frozen stars Kristen Bell and Jonathan Groff will reunite for a new original musical movie.
The pair will star in Molly and the Moon which is being written and directed by How I Met Your Mother creators Carter Bays & Craig Thomas.
The story is based on the real life experiences of Thomas and his wife after they discovered their son Elliot had several heart defects which required open-heart surgery at only two weeks old.
Thomas told Deadline: "My wife made up a little simple lullaby about his name that she would sing to him that just sort of came to her there in the NICU, and that actual melody and lullaby is what we use in the movie.
“The meter of Molly Moon is sort of the same as Elliot. Musicals are always about the first moments that prove why they are musicals."
Sharing more about the movie, he continued: "Kate, our lead character, the mother, is singing a lullaby to her pregnant belly and will sort of push in on that pregnant belly and go into this other world where we see a mysterious little girl in a rowboat in the middle of the ocean, looking up at the moon and hearing that song, hearing that lullaby come through the moon.
"It’s the moment you realize there’s this little soul, this life that wants to exist and be in the world and wants to reach the sound of that voice. She doesn’t know what it means or who it is. It just sounds like love, and she wants to reach it, and that’s sort of the moment that we connect the two worlds of our movie, the world of Molly and the real world that her parents are living in."
Bell will play Kate while Groff will play Molly's dad, Brian.
Harvey Mason Jr (Sing and Pitch Perfect) will be the executive music producer with Stephanie Diaz-Matos (The Get Down) as music supervisor and Nathan Larson the composer.
