The 2013 animation became an almighty hit around the world, with Bell and Idina Menzel voicing sisters Anna and Elsa and performing songs like Let It Go and Do You Wanna Build A Snowman?
Now, Bell has said she wants to officially be too old to play the part in real-life before it gets re-made.
“I think in maybe 10 or 15 years, when sadly we’re all too old to play the roles, that would be cool, much like they did with Beauty And The Beast,” she told the Press Association.
“Frozen 2 is going to come out in 2019 so it would have to be a bit of a wait.”
She suggested: “Then they could write the grandmother in and I could play the grandmother.
“Or I’ll play the Duke of Weselton or something.”
Frozen earned an astronomical $ 1.28 billion, and is the highest-grossing animation of all-time.
Disney have already released live-action takes on Cinderella, The Jungle Book and Pete’s Dragon, with Beauty and the Beast in cinemas this week.
Mulan, The Little Mermaid, Snow White and the Seven Dwarfs, The Lion King, Aladdin, Peter Pan and Dumbo are also on the way.
What’s more, spin-offs for Winnie the Pooh’s Christopher Robin, Peter Pan’s Tinker Bell and 101 Dalmatians’ Cruella De Vil will also hit the big screen, alongside a sequel to Mary Poppins with Emily Blunt in the title role.
The Frozen sequel was officially announced in March 2015, although director Chris Buck admitted “we have lots of things to figure out”.
