Photo Flash: Who Will Walk the Plank? PETER PAN LIVE! Weekend Twitter Roundup!

NBC's PETER PAN LIVE! producer Neil Meron took to Twitter over the holiday weekend to post behind-the-scenes photos of the musical's last rehearsals before its big December 4th debut. Scroll down for a round-up of all the backstage antics, including a couple THANKSGIVING Day shots!

Allison Williams will portray Peter Pan in the highly anticipated PETER PAN LIVE on NBC. The 'Girls' star takes on the role of the boy who refuses to grow up and who is forced to confront the villainous Captain Hook, played by Oscar winner Christopher Walken when the J.M. Barrie's classic musical comes to NBC on Thursday, Dec. 4 at 8 p.m. (ET/PT).

Craig Zadan and Meron will executive produce the broadcast. Emmy nominated for "The Sound of Music Live!," director Rob Ashford won an Emmy as a choreographer for the "81st Annual Academy Awards". Glenn Weiss will serve as director for live television. Musical director David Chase was Emmy nominated for "The Sound of Music Live!" and is one of the busiest music directors working on Broadway today. Always sought after on Broadway for his incredible sets, production designer Derek McLane is an Emmy winner for his work on the 2014 Oscar telecast and was nominated for the 2013 Oscars broadcast. Costume designer Catherine Zuber is a seven-time Tony winner. Lighting designer Robert A. Dickinson has won 19 Emmys for his work on such projects as the Olympic Games, and several telecasts of both THE GRAMMYS and Oscars.
