Fosse, interesting that you would say that Lane would turn Edna to camp when he did the Birdcage and gave a very layered and subdued performance that was anything BUT camp.
Then again I am never sure how anyone can authoritatively say they KNOW how an actor will perform a role. Even the actor doesn't know until they start rehearsal and work with the director.
The demo disc Lane did was just that: a demo for the score. Not a final performance with direction.
Personally, I don't see Travolta in the role but here we go again with Hollywood casting of a movie musical to get the box office. It never works (people don't go see a movie musicals unless they like musicals and then they want to see someone who knows how to sing and dance inf a show). Yes, he did Grease but geez!
It's all about the marketing.
