Entertainment Movies Disney's 'Frozen 3' Announcement Was a Surprise to Franchise's Oscar-Winning Songwriters Kristen Anderson-Lopez and her songwriting partner Robert Lopez penned the Oscar-winning song from the first movie, "Let It Go," and the Oscar-nominated song "Into the Unknown" from Frozen II By Anna Lazarus Caplan Anna Lazarus Caplan Instagram Twitter Digital News Writer, PEOPLE People Editorial Guidelines Published on March 28, 2023 12:26PM EDT Share Tweet Pin Email Photo: Jeff Kravitz/FilmMagic Frozen's Oscar-winning songwriters are ready for the third installment of the franchise — even if they say they were surprised as anyone else that there would be another movie. "They told us, the day of, and a little bit about what they're thinking," Kristen Anderson-Lopez recently told Collider, about how she and her songwriting partner and husband Robert Lopez heard the news. "It got us very excited. Now, we have to let the wheels of Hollywood do what they do, but we were very excited with their ideas." The long-rumored and wished-for Frozen 3, which was officially confirmed by Disney CEO Bob Iger last month in a call with investors, is seemingly set to position the songwriters with plenty of material. The duo's acclaimed songs in the first two films netted them Oscar nominations ("Into the Unknown" from Frozen II) and they won Best Original Song for the massive hit "Let It Go" from the first movie. Idina Menzel Says She's 'On the Fence' About Elsa Having a 'Partner' If 'Frozen 3' Happens The rest of the Frozen ensemble has been open about desiring another sequel. Last June, Kristen Bell, who voices Anna, joked on The Tonight Show, "I would like to officially announce, with zero authority, Frozen 3." When the audience cheered in response, Bell clarified: "Please bear in mind I did say 'zero authority,' 'cause I can't [actually announce it]. I can't do that — I'm not in charge. But there could be something in the works and something maybe happening, maybe." Meanwhile, her movie-sister Elsa (Idina Menzel) has also voiced enthusiasm for the project.
