The artist confirmed his latest project in the Tony Awards press room.
On collaborating with Cyndi Lauper on Kinky Boots, he told Playbill.com, "I was 13 years old when I first saw her in concert, and I can't believe to this day that I'm making music with her."
As previously reported, Avenue Q and Book of Mormon Tony winner Lopez collaborated with his wife, Kristen Anderson-Lopez ("Winnie the Pooh," Up Here), on the score to "Frozen," which will feature the voices of Idina Menzel (Wicked, Rent) as the Snow Queen, Kristen Bell ("Reefer Madness," "Heroes") as Anna and Jonathan Groff (Spring Awakening) as Kristoff.
Chris Buck ("Tarzan," "Surf's Up") and Jennifer Lee direct the computer-animated film musical that is produced by Peter Del Vecho ("Winnie the Pooh," "The Princess and the Frog").
The film is announced for a November debut.
Here's how Disney characterizes the film: "In 'Frozen,' a prophecy traps a kingdom in eternal winter, so Anna (Bell) must team up with Kristoff, a daring mountain man, on the grandest of journeys to find the Snow Queen (Menzel) and put an end to the icy spell. Encountering Everest-like extremes, mystical creatures and magic at every turn, Anna and Kristoff battle the elements in a race to save the kingdom from destruction."
