WATCH: The Extended Trailer For NBC's Live Production Of The Sound Of Music

We are inching closer and closer to NBC's live production of The Sound Of Music and we are finally getting an extended look at the upcoming show. Here's what we learned:

• It's live... in case you didn't hear.
• It'll only happen once. So, wait, does that mean it's live? Yes.
• Carrie Underwood really relates to Maria.
• Stephen Moyer can sing. Touche.
• Laura Benanti basically the Marlon Brando of musical theater.
• It's not Smash but it feels like an extended episode of Smash and it also stars that guy from Smash.

The Sound of Music Live!, airing Thursday, December 5 at 8/7c on NBC.
