It’s almost time for takeoff!

The cast of Peter Pan Live! held their final rehearsals in anticipation of Thursday’s telecast on NBC.

In this first-look shot, Allison Williams (Girls) as Peter Pan and Taylor Louderman as Wendy float through Neverland. The cast also includes Christopher Walken as Captain Hook and Minnie Driver as the adult Wendy/narrator.

Williams told PEOPLE that while the harness to lift her high in the sky is “uncomfortable,” “that first moment when you are lifted off the ground is just utter bliss. It’s a shame we were not built to be airborne.”

Peter Pan Live!, which is NBC’s second attempt at a live performance after premiering The Sound of Music with Carrie Underwood last December, airs Thursday from 8-11 p.m. ET.
