It may still be in the sweltering mid-80s in New York, but Frozen remains on our minds. During the September 2 ABC broadcast of The Story of Frozen: Making an Animated Classic, it was revealed that a new animated short based on the Oscar-winning Disney flick will premiere next spring. The film, titled Frozen Fever, will include a new original song from EGOT winner Robert Lopez and his Frozen collaborator and wife, Kristen Anderson-Lopez. View Comments According to Variety, Frozen Fever will take place on Anna’s birthday, as Elsa and Kristoff plan to throw her a perfect celebration. But Elsa’s wintery powers may get in the way (once again), putting more than just the party in jeopardy. Olaf, the summer-loving snowman, will also make an appearance. No official word yet on whether the movie’s all-star cast will reprise their vocal performances, but we have a feeling they’ll be on board for a little bit more of the global phenomenon. While we all wait, take a look at this clip from The Story of Frozen below, all about that Oscar-winning tune we’re still singing to ourselves. You have Robert Lopez and Kristen Anderson-Lopez at the piano, director/screenwriter Jennifer Lee and some woman named Idina Menzel, all chatting about the journey of “Let It Go” from conception to hitting the big screen.
