Allison Williams has shared the very first picture of her as Peter Pan as she prepares for her roll in the LIVE NBC performance.

The Girls star, will be performing alongside Christopher Walken as Captain Hook!

We can't wait!

Williams, 26, posted the photo on her Instagram saying, "The transformation begins! My first shoot as Pan. 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."
