In an interview with U.K.'s The Telegraph, the actress – who, as the voice of Queen Elsa and singer of the Academy Award-winning song Let It Go – was asked about further Frozen productions to which she answered: "They're all in the works."
While she wasn't sure if she would have much to do with the stage musical she did say she would be part of "the movie hopefully."
"I'm just going along for the ride," Menzel, 43, added.
Frozen was released in November 2013 and has gone on to become the highest grossing animated film of all time grossing $1.27 billion worldwide and the fifth top-grossing movie of all time.
The Disney production, which was penned by writers Jennifer Lee and Hans Christian Anderson and also stars actress Kristen Bell, won two Academy Awards this year for Best Animated Feature and Best Song.
A recent US study by the National Retail Federation found that Frozen is more popular than Barbie these days with 20 per cent of parents planning on buying Frozen-related toys this holiday season – the first time in 11 years Barbie has not occupied the top toy spot on the wish list for girls.
