Jane Krakowski is a Tony winner and she just came off doing a show that won the Emmy for Best Comedy three years in a row, she doesn't need to be the second replacement in a crappy revival (and my comment is more about the poor quality of the production rather than me thinking there's something bad with replacing). She would be hilarious and out of the world funny as Miss Hannigan, but I'm sure that shipped has sailed for her. Honestly, nothing I've seen or heard about this production makes me think that some of the top talent should be spending their time with it, not Mullally and not Krakowski, both of whom I'm sure field offers to headline shows all the time.
Brooke Shields has made a career out of replacing people and doing great work while she's at it. She'd be a perfect fit for this production and might actually bring some fun to it, kind of like Jane Lynch seems to have done. But at the same time, Ruth Sherwood in WONDERFUL TOWN is a hell of a role and that was a great revival, Miss Hannigan can be a great role but not in this mediocre ANNIE, I don't know that Shields wants to spend time away from her kids to be in this. Mary Testa or Jackie Hoffman are probably the only people who'd make this a must-see in my book, they have the power to redefine the entire production.
