While the footage included in the promo came from rehearsals for the musical - the live version will be broadcast on December 4 - it still gave a good look at how the production would look.

Scenes included in the video showed Peter Pan meeting Wendy (Taylor Louderman) in her window, some pirate silliness, Peter teaching the Darlings how to fly, and Peter showing off those flying skills on Hook's pirate ship.

But the highlight of the promo was the big I Won't Grow Up number featuring Peter Pan, John, Michael, and the Lost Boys.

NBC's live event is an update of the 1954 musical adaptation of the Peter Pan story.

Traditionally, a woman has played the title role in all musical versions, hence the casting of Williams in the part of Peter Pan.

Although best known for playing Marnie Michaels on HBO's Girls, Williams also has a history of performing in music and musical theatre.
