When asked about a theatrical stage adaptation, which Disney said is in development, as well as a film sequel that the writers have been quietly working on, Menzel replied, "They're all in the works, ha ha!"

With the stage musical still years away from reaching the stage, Menzel said she would love to be involved in the "Frozen" animated sequel. "Ah, yeah sure… Not the stage show," she said. "I don't know what will happen with that – but the movie hopefully. We'll see. I'm just going along for the ride."

After tipping off fans to the latest "Frozen" developments, Menzel later backtracked on her comments slightly in a Dec. 1 interview on "The Today Show," in which she said, "You know, I have no idea — I just assumed that because it's so successful that's what they're up to!"

Directed by Chris Buck ("Tarzan," "Surf's Up") and Jennifer Lee (screenwriter "Wreck-It Ralph") from a screenplay by Lee, the voice cast of the film features Kristen Bell ("Forgetting Sarah Marshall," The Crucible), Menzel (Wicked, If/Then), Jonathan Groff (Spring Awakening), Tony Award nominees Gad (The Book of Mormon) and Santino Fontana (Cinderella), Alan Tudyk (Prelude to a Kiss) and Ciarán Hinds (Cat on a Hot Tin Roof).

Read the full interview with Robert and Kristen Anderson-Lopez here. Here's how the film, produced by Peter Del Vecho, is described: "Fearless optimist Anna (voice of Bell) sets off on an epic journey—teaming up with rugged mountain man Kristoff (voice of Groff) and his loyal reindeer Sven—to find her sister Elsa (voice of Menzel), whose icy powers have trapped the kingdom of Arendelle in eternal winter. Encountering Everest-like conditions, mystical trolls and a hilarious snowman named Olaf (voice of Gad), Anna and Kristoff battle the elements in a race to save the kingdom."

Additionally, Disney has released a multi-language version of the film's hit song "Let It Go," which can be seen below.
