An extended look at NBC's "Peter Pan Live!" has landed online for viewing pleasure. The new video gives a sneak peek at the actors in costumes as they sing and dance during rehearsal for the upcoming holiday musical event.

Allison Williams as the title character flies and sings in front of the Darling kids in one scene and tries to woo Wendy Darling to follow him to Neverland in another. Christopher Walken's Captain Hook also sings and dances with his crew on the ship.

The scenes are intercepted by interviews with the cast. Williams says she is the "luckiest girl ... the luckiest boy-girl in the world" for landing the role. She sings praises for Walken, "He is so deeply cool. Even when he's not doing anything, he is better at acting than I've ever been. Even when he's just sitting around, he's funnier than I've ever been."

Walken himself enjoys doing the show that brings him back to his musical roots. "It's been fun - I dance a little, I sing a little," he says, "That's what I do."

"Peter Pan Live!" also stars Christian Borle as Mr. Smee and George Darling, Kelli O'Hara as Mrs. Darling, Taylor Louderman as Wendy Darling, Alanna Saunders as Tiger Lily, Jake Lucas as John Darling, and John Allyn as Michael Darling.

Adapted from the classic Broadway musical which was based on the famous classic tale, the holiday musical event is directed by Glenn Weiss with Craig Zadan and Neil Meron as executive producers. It will air Thursday, December 4 from 8 to 10 P.M. on NBC.
