"Not gonna lie, the bigness of it felt scary for a hot second."
That was Girls star Allison Williams' first reaction to donning the iconic tights of the boy who never grew up in Peter Pan Live!, NBC's next major live production, set to air on Dec. 4.
We're taking you behind-the-scenes of the highly anticipated musical, also starring Christopher Walken as Captain Hook, in the exclusive video above, which gives viewers their first look (and listen) at Williams in action as Peter Pan. Oh, and you finally get to hear Walken belt out a tune about Hook's "cute" hook.
Yes, we are already planning our viewing parties!
"It's been fun," Walken says of tackling the villainous role. "I dance a little, I sing a little, you know, that's what I do!" But Walken admits the fact that they are performing live is "intimidating."
Still, Williams promises that Walken "will not disappoint" in the role.
Christian Borle, who also starred in NBC's highly-rated live production of The Sound of Music last year, takes on two roles in the production, Smee and Mr. Darling, and promises Peter Pan will be an event "the whole family can tune in and watch...new songs and a new script and Christopher Walken. Enough said."
To hear more from Williams, Walken and the rest of the cast, watch our exclusive video above!
The Peter Pan cast also includes Kelli O'Hara (Mrs. Darling), Taylor Louderman (Wendy) and Alanna Saunders (Tiger Lily).
Peter Pan Live! airs Thursday, Dec. 4 on NBC.
(E! and NBC are both part of the NBCUniversal family.)
