As Marcus "Dizzee" Kipling, a psychedelically gifted young graffiti artist, Luhrmann promises that you'll see another side to Smith -- who perhaps is best known for wearing minimalist cosplay to weddings and waxing poetic on Twitter.
"It's a tremendous role for him," Luhrmann told MTV News back in July. Not only has Smith taken lessons from legendary graffiti artist Lady Pink, but he's also been immersing himself in the turbulent history of the Bronx. Oh, and "he rocks a great 'fro."
"The Get Down" focuses on a group of creative teenagers growing up in the South Bronx in the '70s and how the near bankrupt city birthplace of hip-hop in New York City. "We're in a time, in '77, at the beginning of hip-hop," Luhrmann added. "It's wasn't even called hip-hop at that time. But there's also disco -- disco was king in '77. Punk was emerging as quite the underground force. It was this amazing matrix of music."
Smith joins an impressive young cast that includes "Paper Towns" star Justice Smith, "Dope" breakout Shameik Moore, Skylan Brooks and Tremaine Brown Jr.
"They are some of the great young actors of this generation," Luhrmann said. "In this show, they get to play all the strings of their instruments. You're really going to see them in a different light. I think people will be surprised, yet again, by what these young talents have to offer."
Rapper Grandmaster Flash will not only guest star on the series, but he also serves as an associate producer and advisor.
"The show is so music based," the director said. "I'm working with Grandmaster Flash, who is in it as a very interesting character, and a few other veterans of this scene, and they're contributing [to the project]. Honestly, it's revitalizing for all of us, to be around that kind of young talent."
Luhrmann, known for his colorful tales of overwrought excess, is excited to bring his lush aesthetic to the streets of South Bronx -- because at the heart of "The Get Down" is a cultural movement.
"The city was in its most dramatic moment, and out of that came such a cultural force, such creativity," he said. "And that's what drew me to it. I'm so interested in this idea that out of so little, came so much creativity."
