Girls star Allison Williams has been cast as the lead in NBC's telecast of Peter Pan Live!
In a statement, Williams, who said she has wanted play Peter Pan since she was three years old, called the casting "a dream come true."
She will star opposite Christopher Walken, who was recently cast as Captain Hook.
Williams graduated from Yale in 2010, where she was a member of a College Musical, a group that would create theatrical clips for YouTube. She covered "Breaking Free" from High School Musical with a friend.
She also covered "Tic Toc" by Ke$ha.
And, legend has it, her Mad Men remix video helped her get cast on Girls.
And Williams' Girls character, Marnie Michaels, also became known for the music video she made of Edie Brickell's "What I Am" that accidentally wound up on YouTube in Season 3.
Here's hoping Williams' performance in Peter Pan Live!, which airs on NBC on December 4, 2014, is greeted with less notoriety than Marnie's musical efforts.
Allison's father, NBC Nightly News anchor Brian Williams, reported the casting on air Wednesday night hours after the announcement was made. And he sounded like any proud father would in the situation: "Family members confirm she's been rehearsing for this role since the age of three and they look forward to seeing her fly."
