Elsa, Anna and Olaf could all be returning to the big screen soon in "Frozen 2." Idina Menzel (who voiced Elsa) told the Telegraph in an interview that Disney was already working on a sequel to the hit animated movie.

Menzel was asked about the endless rumors that Disney was working on another "Frozen" movie and a stage musical, when she said, "They're all in the works." The studio also has plans to release a six minute short to be released in theaters around Christmas.

Disney has yet to confirm that a "Frozen 2" is in the works but Menzel told the Telegraph that she expects to be invited back to reprise her role as Elsa in the movie version.

"Not the stage show - I don't know what will happen with that - but the movie hopefully. We'll see. I'm just going for the ride," she said.

The 43-year-old actress also told the Telegraph that she's still shocked that young girls recognize her as the person who belted the tune "Let It Go" and other songs from the movie.

"I remember some of those classic Disney songs from movies, and you knew the character but you didn't know the person behind the song. But this is different, this is weird," Menzel told the Telegraph. "I can't give any tips on how to sing 'Let It Go' because I barely can sing it sometimes. It's really hard. I can't wake up in the morning and just sing it."

"I guess my advice is that everyone who likes to sing it should sing it loud and proud and karaoke it out, sing it in the shower, sing it in the car and don't worry about hitting the high notes."

"Frozen" told the story of sisters Anna (voiced by Kristen Bell) and Elsa as they tried to save Arendelle from winter.

"Fearless optimist Ana sets off on an epic journey - teaming up with rugged mountain man Kristoff and his loyal reindeer Sven - to find her sister Elsa, whose icy powers have trapped the kingdom of Arendelle in eternal winter. Encountering Everest-like conditions, mystical trolls and a hilarious snowman named Olaf, Anna and Kristoff battle the elements in a race to save the kingdom."
