LOS ANGELES (Reuters) - Mahershala Ali won the best supporting actor Oscar on Sunday for his role as a drug-dealing mentor to an impoverished black boy in the intimate independent drama "Moonlight."
Ali, 43, plays Juan, a drug dealer who takes a young black boy living in Miami with a drug-addict mother, under his wing.
It was the first Oscar win and nomination for Ali who was considered the frontrunner in the category after winning a slew of earlier awards for his performance.
Accepting the award on stage, Ali thanked his teachers.
"One thing that they consistently told me ... is that it wasn't about you," Ali said. "It's not about you. It's about these characters. You are in service to these stories and these characters."
In "Moonlight," Ali's Juan teaches young Chiron to swim and encourages him to not be weighed down by his environment but rather to carve his own destiny.
Ali also appeared in another Oscar-nominated movie this year, "Hidden Figures," in which he plays a U.S. colonel who woos Taraji P. Henson's black female mathematician in the 1960s.
The Oakland, California, actor is probably best known for playing former White House Chief of Staff Remy Danton in Netflix's political drama "House of Cards," and conniving Cottonmouth in Netflix's Marvel superhero series "Luke Cage."
Ali's career has spanned television, film and theater. He started out playing a doctor on TV series "Crossing Jordan" in 2001, and since then has had roles in dozens of projects including TV series "Treme" and "Alphas."
