Nino Munoz/NBCHere's Peter Pan! Allison Williams will be the boy from Neverland in NBC's Peter Pan Live! airing this December. The Girls star debuted the first photo of herself in character on NBC's Today. Christopher Walken will take on the role of Peter Pan's nemesis, Captain Hook.
Williams said the process of playing Peter Pan is "so fun." "I can only imagine what the next couple of weeks and months are going to bring. I cannot wait," she said on Today.
Like NBC's Sound of Music broadcast last year, Peter Pan will be live. "We're so excited about the live part of it," she said. "I think that's what makes it so fun."
Williams is wearing a wig as Peter Pan, but she offered to cut her hair for the part.
"I have wanted to play Peter Pan since I was about 3 years old, so this is a dream come true," Williams said in a statement when her casting was announced in August. "It's such an honor to be a part of this adventure, and I'm very excited to get to work with this extraordinarily talented team. And besides, what could go wrong in a live televised production with simultaneous flying, sword fighting and singing?"
Peter Pan Live! hails from Smash and The Sound of Music Live! producers Neil Meron and Craig Zadan. NBC's live version of the classic musical is based on the original Broadway production which was based on the book by J.M. Barrie.
"Allison Williams is a major find," Zadan and Meron said in a statement. "She will reinvent the iconic role of Peter Pan with her wit, her warmth, her dynamic flying and her wonderful musical abilities. The score will be sung beautifully and introduced to a whole new generation of families."
Peter Pan Live! comes to NBC on Dec. 4.
