NEW YORK: Soon, a determined girl named Dorothy will ease on down that road in NBC’s The Wiz Live!

Her odyssey began in 1900 with the publication of L. Frank Baum’s The Wonderful Wizard of Oz, then continued with the classic 1939 movie musical starring Judy Garland, followed by the 1975 Broadway production of The Wiz (which, billed as “the Super Soul Musical,” won seven Tonys, including best musical) and, in 1978, by the film starring Diana Ross.

To transform The Wiz yet again, this time into a live TV extravaganza, is anything but easy.

For weeks the star-studded cast (including Elijah Kelley, Ne-Yo, David Alan Grier, Mary J. Blige, Queen Latifah, Uzo Aduba, Common and newcomer Shanice Williams as Dorothy) has mustered at Long Island’s Grumman Studios (the one-time Grumman aeronautics complex where the Apollo lunar module was built that put man on the moon). In free moments, they and the executive producers of The Wiz look ahead to 8 p.m. Thursday, and their one-night-only trip to Oz.

Why The Wiz: “People think, ‘Oh, you’re doing The Wiz because Empire is such a big hit,’?” says Craig Zadan, who is producing the show with his longtime partner Neil Meron. “The truth is, staging this musical has been a dream of ours since the ’90s, but the rights were tied up. It’s just coincidental that, this year, when we were choosing a new musical, the rights were cleared.”

“Both of us loved the original Broadway production,” says Meron. “But The Wiz is a cultural touchstone in the black community, with an emotional connection we didn’t really know about until we were doing it. Bottom line: The Wiz is phenomenal entertainment, and even with the racial divide at its highest point in decades, we want to put that on pause and do something for the family and for the spirit, and have a great time.”

A timeless message: Kelley (who co-starred in Hairspray and plays the Scarecrow): “Understanding the ability to conquer your fears is one of the things that propels you to any success you desire. That’s what The Wiz is about.”

Grammy-winning singer-actor Ne-Yo (the Tin Man): “Everybody thinks, ‘I’m not pretty enough,’ ‘I’m not thin enough,’ ‘I’m not this-or-that enough.’ But none of that is true. The Wiz teaches you that everything you need to make your dreams come true is already there inside you.”

In Dorothy’s shoes: Williams, a 19-year-old New Jersey native chosen from hundreds of hopefuls, had already appeared in her middle-school production of The Wiz. But she had been “too scared” to try out for Dorothy, instead scoring the part of Addaperle, Good Witch of the North.

“But when there was an open call for the TV production, I went, just for the learning experience,” she says. “Then they kept calling me back and calling me back. There was finally a point where I was like, ‘Hold on! I might actually get this.’ Now I’m having the time of my life!”

And at her side is Stephanie Mills, who here plays Auntie Em but was the original Dorothy in the Broadway production.

Dressed to kill?: Actor-comedian Grier (on his Cowardly Lion getup): “It is SO very hot, sir! I’m a fuzzy stovepipe!”

Ne-Yo (on his Tin Man costume): “It’s 30 or 40 extra pounds. And it doesn’t breathe!”

Kelley (on his Scarecrow duds): “The costume isn’t heavy, but I have to always stand like this,” and he demonstrates an ache-inducing bandy-legged posture. “What I don’t have to deal with in my costume, I make up for with muscle contortion.”

High hopes: For Ne-Yo, the biggest challenge is “trying to figure out what you can bring to the role. There’s no topping Diana Ross or Michael Jackson (the film’s Scarecrow) or Nipsey Russell (its Tin Man). Instead, you have to ask yourself, ‘How can I add to the legacy of my character?’ ”

Meanwhile, Zadan and Meron hope to continue their partnership with Cirque du Soleil and take this new production to Broadway next year.

An important visual device: digital effects played across huge LED panels, like the tornado: “It’s incredible!” says Zadan. “We’re going in visual directions that are new to television.”

Nerves?: Just before airtime, Ne-Yo will be telling himself: “You know what you’ve rehearsed for, so get out there and do what you know you can do and just be great!”

“I’m ‘anticipitatious,’?” says Grier. “I’m anticipating the anticipation. But that’s GOOD nerves. We’ll be ready!”

“If you don’t pray, worry,” says Williams. “But don’t worry, if you’re gonna pray. And I’m praying every day.”
