That's fair. My only point is that Lea Michele is Event Casting for this particular role due to a rather unique set of circumstances. It's not a stunt in the sense that she is obviously qualified to play the role. She sang its most famous song at the Tony Awards a dozen years ago along with a bunch of other Funny Girl songs on her hit TV show. It's an event because people saw her sing the songs on Glee.
I can't think an actress so associated with a role who had, until a few weeks ago, never actually played the role on stage anywhere.
