'Moonlight' Trailer: Naomie Harris, Mahershala Ali Offer Guidance Amid Miami's War on Drugs

The Barry Jenkins drama is based on the Tarell McCraney play 'In Moonlight Black Boys Look Blue' and marks the big-screen debut of Janelle Monae.

"At some point, you gotta decide for yourself who you gonna be," says Mahershala Ali in the trailer for Moonlight. "Can't let nobody make that decision for you."

Written and directed by Barry Jenkins, the drama from A24 and Brad Pitt's Plan B Entertainment follows a young boy named Chiron, who is coming of age in War on Drugs-era Miami. Based on the Tarell McCraney play In Moonlight Black Boys Look Blue, the story is told across three defining chapters in his life as he experiences the ecstasy, pain and beauty of falling in love, while grappling with his own sexuality.

The cast features Naomie Harris, Andre Holland, Trevante Rhodes, Alex R. Hibbert, Jaden Piner, Ashton Sanders and Jharrel Jerome, as well as Janelle Monae in her big-screen debut.

Moonlight opens in select New York and Los Angeles theaters on Oct. 21, following its premiere at the Toronto Film Festival.
