Allison Williams lands title role in NBC's "Peter Pan Live!"

"Girls" star Allison Williams has landed the leading role in NBC's "Peter Pan Live!"

The 26-year-old actress and classically trained singer will star opposite Christopher Walken as Captain Hook later this year in the live musical production, the network announced Wednesday.

"We couldn't be happier that Allison Williams is our Peter Pan," said Robert Greenblatt, Chairman, NBC Entertainment. "She's a lovely rising star on the award-winning show 'Girls' -- where she occasionally shows off her incredible vocal talent -- and we think she will bring the perfect blend of 'boyish' vulnerability and bravado to save the day against Christopher Walken's powerful Captain Hook."

Williams plays Marnie Michaels on HBO's "Girls," for which she has recorded several songs. She is the daughter of NBC News anchor Brian Williams and has also appeared on "The Mindy Project" and "The League."

"I have wanted to play Peter Pan since I was about 3 years old, so this is a dream come true," said Williams. "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," she added, "what could go wrong in a live televised production with simultaneous flying, sword fighting and singing?"

"Peter Pan Live!" comes on the heels of NBC's successful "The Sound of Music Live!" last year, with Carrie Underwood, Stephen Moyer and Audra McDonald. That telecast drew nearly 19 million total viewers, TVLine reports.

The live "Peter Pan" production will air Dec. 4.
