Straight Outta Compton‘s Keith Stanfield has taken the lead role in director Matt Ruskin’s upcoming untitled film based on the story of wrongfully convicted prisoner Colin Warner. Warner was an 18-year-old kid in crime-ridden 1980 Brooklyn, was wrongly identified by a witness and ultimately sentenced to 15 years to life in prison. He would spend 20 years in prison, supported by his lifelong friend Carl King who, despite having no formal legal education, obstinately fought to prove Warner’s innocence. Warner was eventually freed in 2001, more than a decade after the real killer came forward.

Joining Stanfield is Nnamdi Asomugha (Hello My Name Is Doris), who will play King. Ruskin will direct from his own script, and Lila Yacoub (Rosewater, Moonrise Kingdom) will produce. From Black Maple Films and iAm21 Entertainment, filming begins September 9 in New York City. A portion of the proceeds from the film will go to help those wrongfully convicted.

Stanfield will next be seen in Straight Outta Compton, Oliver Stone’s Snowden, and Don Cheadle’s Miles Ahead. He’s repped by Innovative, Colin Stark and attorneys Lev Ginsburg and Grace Kallis. Asomugha is repped by CAA, Radius Entertainment and attorney Deborah Klein.
