I would say this is the role that finally delivered on Blunt's promise from years ago. She had been doing consistently steady work but had yet to get a part that was as rich and central to the story (I do hear she was wonderful in EDGE OF TOMORROW, but I doubt the role is as great as the Baker's Wife), and she sure went with it. This is a pretty definitive performance from her.
"No More" is a brilliant song, I just don't see a place for it in this version. With the Mysterious Man gone, some of the lyrics don't have the same impact, and the movie just needed to end. I don't think Marshall said we shouldn't be upset it's gone; in fact, at the live Q & A on Yahoo I recall him saying it hurt him to cut the song, but that it would've hurt the flow of the film. He also said something like "you think you want to see the show on stage, but you don't." I just think it was a smart cut, and the scene works beautifully, with Corden's breakdown being one of the emotional highlights of the film.
I did miss "Maybe They're Really Magic," one of the most illuminating songs about the Baker's Wife, and it's so short I wish they'd kept it.
"Some people can thrive and bloom living life in a living room, that's perfect for some people of one hundred and five. But I at least gotta try, when I think of all the sights that I gotta see, all the places I gotta play, all the things that I gotta be at"
