Maria, former would-be nun, is about to get married.
Starring as Maria in NBC's new version of "The Sound of Music," Carrie Underwood is clad in her own T-shirt and leggings plus a wedding veil as she reverently steps through the bare-bones Manhattan rehearsal space while three dozen castmates, on their feet as if in church, sing "How do you solve a problem like Maria?"
"The Sound of Music Live!"Premieres at 7 p.m. Thursday, Dec. 5, on NBC. A "Sound of Music Live!" album will be released on Dec. 3; a home-video edition of the broadcast goes on sale Dec. 17.
Underwood's procession ends at the "altar" (marked by a music stand) to join her groom, Capt. von Trapp, played by Stephen Moyer.
During this preliminary run-through a few weeks ago, much work clearly remained to get "The Sound of Music Live!" ready for airtime on Thursday, Dec. 5, when it, along with everyone involved, will make history: More than a half-century has passed since a broadcast network has dared to mount a full-scale musical for live TV.
It would have been risky enough revisiting this Rodgers and Hammerstein classic on any terms. But this is no remake of the not-to-be-tampered-with Julie Andrews juggernaut, declares Neil Meron. Meron and longtime partner Craig Zadan are the telecast's Oscar-winning executive producers.
Instead, "The Sound of Music Live!" is the 1959 Broadway musical reimagined for TV, then given extra crackle with a live presentation.
Meron's message: Everybody knows "The Sound of Music," or thinks they do from the 1965 film. But relatively few fans are acquainted with the stage original. Drawing from it, "The Sound of Music Live!" is meant to feel familiar, yet at the same time come across as new and different.
Consider: Moyer with castmates Laura Benanti (as Baroness Elsa Schrader) and Christian Borle (as Max Detweiler) are rehearsing a couple of weeks later a saucy song titled "How Can Love Survive?" This song will be brand-new to most viewers of the telecast -- it was dropped from the movie.
This number, sung to an instrumental track recorded by a 40-piece orchestra, takes place on the sumptuous von Trapp terrace, complete with a fountain and a panoramic view of the Alps.
The entire production has redeployed to a cavernous Long Island, N.Y., soundstage.
Grumman Studios' Stage 3, with square footage rivaling a football field's, is now home to the terrace, along with five neighboring sets evoking pre-World War II Austria including the abbey, a festival site draped with huge swastikas and the summit over which (spoiler alert) Maria, the Captain and his seven children pass to flee the Nazis at the musical's conclusion.
It is for this soaring finish that Audra McDonald reprises "Climb Ev'ry Mountain," the breathtaking anthem that Mother Abbess introduces as she sends Maria into the world and into the von Trapp household.
"In that scene, Mother Abbess is giving Maria tough love, kicking her out of the abbey," says McDonald. "But Carrie is so moving and so sweet, my challenge is to not cry when I sing it."
When she sings it, McDonald is fully capable of bringing to tears everyone within earshot. She is a classically trained soprano, a Tony- and Grammy-winning singer and stage actress who appeared for four seasons on ABC's "Private Practice."
Though best known as a vampire on HBO's "True Blood," Moyer, too, is a theater veteran. Last summer he returned to what he calls his first love, the musical stage, after 18 years' absence for a production of "Chicago" at the Hollywood Bowl. Then he reported for work on "The Sound of Music Live!"
And then there's Carrie Underwood. Despite her status as a multiplatinum country music superstar who rose to fame as the winner of "American Idol" in 2005, at first glance she might seem something of a wild card in the "Sound of Music" cast.
"Carrie is one of the bravest artists we've ever worked with," says Meron, who notes that she arrived two weeks before the production's six-week rehearsal began with her lines fully memorized, to get a head start.
"Every day," she says during a break, "I feel like I discover new things and how to go places in acting that I didn't think I could go."
Even if she's a drama neophyte as she faces her "Sound of Music" trial by fire, Underwood, by one measure, is the cast's old hand: No one knows live TV, and its pressures, like she does.
"But this time, there's no chance of me being voted out," she laughs. "I'm here to stay."
