The pair led the original 2003 Broadway cast of the Oz-based musical, with Menzel playing Elphaba and Chenoweth starring as Glinda, reported Digital Spy.
Asked if she had been approached about a role, Menzel joked, "Yeah, as the mother of Elphaba. I would die to be in the film, except I'm afraid Kristin Chenoweth and I... They told us we're a little over the age for that."
"If I could be a part of it in some way, that would be great. But I already feel like I received - and continue to receive - the gifts from 'Wicked' and how it affects audiences," Menzel said.
