Disney's Frozen was one of the most talked about movies of 2013, taking in just over $400 million domestically and over $1.2 billion worldwide during its theatrical run, making it the highest-grossing animated movie of all-time, and fifth best among all movies. The studio did announce in September that they are making a short film entitled Frozen Fever, set to debut next spring. There are also Frozen characters appearing on ABC's Once Upon a Time, with a stage musical currently in development and a Frozen attraction debuting at Disney World in 2016. So what about a sequel?

With all of its success, many have wondered why a theatrical sequel to Frozen hasn't been announced yet? For a while, it looked as though Disney had no interest in pursuing a big screen follow-up. But during an interview with The Telegraph, voice actress Idina Menzel, who portrays Elsa, claims that the sequel, the stage musical and the short film are all in development. Asked what she can say about a sequel and the stage show, the voice actress responded:

" That they're all in the works, ha ha!"

When asked if she had signed on to reprise her role as Elsa once again, Idina Menzel said she won't be a part of the stage musical, but hinted that she will "hopefully" be back for the movie sequel.

"Ah, yeah sure... 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."

It isn't known if a screenplay is being developed at this time, or if Frozen directors Chris Buck and Jennifer Lee will be back at the helm. It's worth noting that Disney does have an unspecified movie set for release in November 2018, but it isn't known if this is being held for a Frozen sequel. We should also point out that when Idina Menzel says 'movie', its entirely possible that she is talking about the upcoming short. Would you like to see a theatrical follow-up to Frozen?
