VIDEO: Allison Williams on Fueling to Fly in NBC's PETER PAN LIVE!

Allison Williams recently spoke to ET about how flying for NBC's upcoming PETER PAN LIVE! has left hard-earned bruises and kicked up her appetite for donuts, bagels and "everything sinful" to keep her fueled. Watch the interview below!

PETER PAN LIVE! airs Thursday, December 4 at 8pm/7c. The beloved Broadway musical, filled with songs such as "I'm Flying," "I Won't Grow Up," "Never Never Land" and "I've Gotta Crow," is re-imagined with Williams ("Girls") playing the title role of Peter Pan and Walken, an Oscar winner and Emmy and Tony Award nominee, as the villainous Captain Hook. Oscar nominee Minnie Driver plays the role of narrator and adult Wendy Darling.

Also co-starring in "Peter Pan Live!" is Tony winner Christian Borle, who will play both Smee, the dastardly right-hand to Captain Hook, as well as George Darling, the no-nonsense father of the Darling children. Five-time Tony nominee Kelli O'Hara co-stars as Mrs. Darling.

The live holiday spectacular is based on the original 1954 Broadway production of "Peter Pan," directed and choreographed by Jerome Robbins, with a book by J.M. Barrie. Mary Martin starred as Peter and Cyril Richard as Captain Hook. The story of "Peter Pan" is one of eternal youth, companionship and enduring loyalty. A mischievous boy who can fly and doesn't age, Peter spends his never-ending childhood on the enchanted island of Never Land where he is the leader of the Lost Boys. With the fairy Tinker Bell always at his side, he brings Wendy Darling and her brothers to Never Land on the biggest adventure of their lives.
