Brian Williams may make the world seem less complicated every evening on the Nightly News, but his daughter Allison has come to give confused feelings to Wendys and Lost Boys alike in the upcoming NBC special Peter Pan Live! on Dec. 4th. The Girls actor shared this photo on her Instagram, writing:

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
