Allison Williams Allison Williams

It seems like just yesterday that NBC's The Sound of Music Live! sent Twitter into overdrive as viewers dispatched snarky tweets about Carrie Underwood's stiff acting and supportive thoughts for #TeamElsa. However, nearly a year later, the network is now getting ready to make live TV magic — or should we say mistakes — with Peter Pan Live!

Celebrity Halloween costumes that might even be too sexy

A new teaser released Thursday offers a sneak peek at Girls star Allison Williams looking a bit green — get it? — in her costume as her feet leave the floor. And then there's the new footage of Christopher Walken in his full Captain Hook get-up, hook and all, dueling with Williams. Does he look intimidating as the famous children's tale villain? Or just very Walken-esque? Or both? Check out the video below and judge for yourself:

Peter Pan Live! airs on Sunday, Dec. 4 on NBC. Will you watch?
