She's off to Neverland. NBC released the first photo of Allison Williams in costume as Peter Pan from "Peter Pan Live," which will broadcast on the network on Dec. 4. The "Today" show tweeted the pic, which shows Williams in a cropped wig, a torn green suit, some mesh and brown boots

Williams was cast as Peter Pan in July, and at the time she said, "I have wanted to play Peter Pan since I was about 3 years old, so this is a dream come true."

Williams also posted the photo to her Instagram account and said, "Fun fact: I was all ready to cut my hair, then was told by the folks who actually know what they're doing that a wig works better for everybody. So, December 4th, here we come. #wiglife #peterpanlive #nbc"
