Grease: Live is coming to TV on Sunday, and ET has the breakdown on what it’s taking to make the one-night production a reality.
The live, three-hour event -- a reintroduction and re-imagination of one of the most iconic musicals of all time -- is costing $16 million to put on across two soundstages and 21 sets.

The show stars Julianne Hough as Sandy, Aaron Tveit as Danny, Vanessa Hudgens as Rizzo, Carly Rae Jepsen as Frenchy, Kether Donohue as Jan, David Del Rio as Putzie, Carlos PenaVega as Kenickie and Keke Palmer as Marty. Even though this experienced cast feels fully prepared after roughly two months of intense rehearsals, there are plenty of reasons for both them and the crew to have butterflies.
"The dancing is no joke," Hudgens told ETonline’s Leanne Aguilera earlier this month. "We are sweating through our clothes day in and day out.”

Hough assured us that while this won't be your parent's Grease, it will still include some of your favorite quotes from the classic movie.
"We're not trying to recreate and do it exactly," Hough explained. "There's definitely some lines that are so iconic that when you hear [them], you just think Grease, so maybe we have to do the line a little bit like that, otherwise you'll be disappointed."
As the premiere date has gotten closer, the cast has grown more excited to perform live. "It feels so real now," Hough said.
