“He might be the first tap-dancing Hook you’ve ever seen,” NBC Entertainment Chairman Bob Greenblatt said in announcing Christopher Walken’s casting in Peter Pan Live at TCA in July. No sign of that in this photo tweeted by exec producer Neil Meron today, but the Oscar-winning actor certainly has his game face on. NBC will air the revered musical live on December 4, starring Allison Williams as the boy who refuses to grow up. The cast also includes Kelli O’Hara, Christian Borle, Taylor Louderman and Alanna Saunders. Craig Zadan also exec produces.
