Just in time for Elsa and Anna's visit to Storybrooke, ABC will air The Story of Frozen: Making a Disney Animated Classic, an all-new, original special that ventures behind-the-scenes for an exclusive look at the origins and evolution of Frozen, airing TUESDAY, SEPTEMBER 2 8|7c.

Viewers will get a rare look inside Walt Disney Animation Studios and unprecedented access to the creative team that brought Frozen to life. The special will also include a never-before-seen preview of Frozen's Elsa and Anna on Once Upon a Time.

Throughout the one-hour special, the audience will hear from Frozen stars Kristen Bell and Idina Menzel, the directors Jennifer Lee and Chris Buck, songwriters Kristen Anderson-Lopez and Robert Lopez, producer and artists and chief creative officer — the team who dreamed of making a cherished Hans Christian Andersen story into a big screen animated musical.
