Menzel, 43, teased the possibility of a sequel, stage adaptation and a 'Frozen' short in an interview with the Telegraph.
"...They're all in the works! I don't know what will happen with that, but the movie hopefully. We'll see. I'm just going along for the ride," Menzel said.
The Broadway veteran, who voices Elsa in the film, has enjoyed mainstream success with the film's theme song 'Let it Go' since its release in November 2013. Frozen has also inspired wedding dresses, Halloween costumes, and "Let it Go" music covers. The song won Best Original Song at the Oscars in March.
