According this THIS report, it's Anne Hathaway. I think she's a great choice, however, I would've liked to see Zooey Deschanel in at least one of the Garland roles, be it stage or screen. It does seem like a bit of a monopoly to give Anne both cracks at it. But I do think she'll do a wonderful job.Speaking of Zooey Deschanel, where is that girl? I haven't seen her since, "Yes Man". She has such an incredible singing voice. I'd love to see her in a musical.
