ET caught up with the 18-year-old actor at Variety's Power of Young Hollywood Issue Celebration in Los Angeles on Tuesday, where he talked about the influence Dr. Martin Luther King Jr.'s work had on his new clothing line collection, MSFTSrep.
"I just dropped a collection today and, you know, every inspiration for every collection is something different every time, but right now the inspiration I use is Martin Luther King," Smith told ET's Katie Krause at the event, presented by the app Pixhug with Vince Camuto.
"He wrote a letter when he was in Birmingham in a jail cell, and he wrote this letter, and he said a lot of powerful, powerful, powerful things in his rhetoric inside of this masterpiece that he wrote, which is just so beautiful," he explained of how the civil rights leader had inspired his line.
"But the thing I took away is non-violent, direct action programs… and I just feel like that was written so long ago, but it applies so much to what's happening right now in the world," Smith said. "So that's why I want to give it to the kids. I want the kids to…you know, rep[resent] that non-violent, direct action program of doing exactly what you see that you need to do, and changing the world."
"That's what MSFTSrep is all about -- empowering the youth," the After Earth star added.
Empowerment is a big part of Smith's new clothing line, and how he lives his day-to-day life, but it's being able to "share our feelings" that he thinks young people need to focus on.
"I think we should talk about our feelings more and how we feel," he said. "I feel like we should just talk about the truth more, you know? That's it and just how we feel about life for real."
Smith was more than happy to share his feelings about his new Netflix show, The Get Down.
"I'm so happy to be a part of Netflix," he boasted. "I'm so happy to be a part of a show that’s involving hip hop. I'm so happy to be a part of a show that Grandmaster Flash is involved with, that Nas and [co-creator and executive producer] Baz Lurhmann… like all my dreams are coming true at the same time."
Smith wasn't the only young star to open up at Tuesday's event.
ET also caught up with Modern Family star Ariel Winter, who gushed about her plans to attend UCLA and revealed she wants to major in political science.
"I've been acting my whole life, so I feel, for me… I feel like I should have knowledge in another subject, because the industry is so… you can't predict what's going to happen," she said. "I could be working now and then not work the next 10 years. So, I thought it's important to have knowledge in another subject that you like, that you can have as a plan in the future."
