Idina Menzel confirms the "Frozen 2" movie is already in the works.

The voice of Elsa in "Frozen," Idina Menzel offered a sweeping comment on rumors of the "Frozen 2" movie and a stage musical adaptation of the original: "They're all in the works."

Menzel's confirmation is the latest news on the sequel to last year's blockbuster hit. "Frozen" earned $1.2 billion worldwide, and is currently the highest-grossing animated feature of all time. Disney will screen a six-minute short film teaser this Christmas; "Frozen Forever."

Menzel is expected to reprise her role as Elsa on-screen, for the rumored sequel; she's identified so much to her Elsa character that young girls recognize and approach her on the street. It's unlikely she'll be listed for the theatrical production, though.

"Not the stage show - I don't know what will happen with that - but the movie hopefully. We'll see. I'm just going along for the ride." (telegraph.co.uk)

Walt Disney's CEO Bob Iger has previously confirmed "Frozen" had real franchise potential, and the studio is considering extending the "Frozen" universe, which includes the stage adaptation.

"There's a lot of active development. You will see Frozen in more places than you see today. ... This has real franchise potential. We expect to see not just new product but continued interest in this and continued impact on the bottom line for quite awhile. Its success speaks volumes on the future of animation at our company."

Rumored for the "Frozen 2" cast include Benedict Cumberbatch, Jamie Foxx, and Judi Dench; a Forbes report insists a sequel is in the bag, banking on the first movie's box-office revenues.

"Disney foregoing another round in Arendelle is basically tantamount to passing up free money in the hundreds-of-millions. That they haven't out-and-out committed and may leave it without a sequel shows something vaguely resembling artistic integrity as a matter of company policy."
