call me crazy, but if reese witherspoon decided to tackle broadway, i doubt it would be to rehash a role she's already done, several years ago, before she was a Serious Actress.
having sung a lot of it, i can say that larry o'keefe's music for women tends to be really hard and high and belty. plus, there aren't that many young bway girls who can carry a show.
it's not the easiest role to cast. the buzz on laura bell bundy is really good. playing elle not only requires a lot of comedic ability and spirit, but also a sweetness and lack of guile that makes you root for her. if they like her, i hope they keep her and don't stunt-cast it with some tv star who can't do it justice.
