That would be a terrible career move, and I hate making this kind of statements but she is so above being in a show that casts so many people who have no business being on a Broadway stage. Also, Zeta-Jones' brilliant take on Velma doesn't work for the revival's more vaudeville and less serious approach. It'd be great to see her perform "All That Jazz" live at some benefit or to hear her recording of some of the songs that were cut, but her performance as Velma Kelly already lives on in the film, there's no need for her to do the stage version.
I hope this isn't her only Broadway outing, it'll be great if she started doing more stage work, especially since she hasn't gotten any film role as good as Velma since she won the Oscar.
