Thurgood Marshall will forever be revered as the first African-American Justice of the U.S. Supreme Court—a man who helped decide crucial cases like Brown vs. The Board of Education, which laid the framework for the entire Civil Rights Movement.

In the new film Marshall, a young Thurgood Marshall (Chadwick Boseman) is sent by the NAACP to Connecticut to defend a black chauffeur (Sterling K. Brown) accused of both sexual assault and attempted murder by his wealthy, white employer (Kate Hudson). Partnered with a young Jewish lawyer named Samuel Friedman (Josh Gad), an unlikely duo is formed, as they become the accused man’s only hope.

The film tells the heroic rise of Thurgood Marshall before he becomes a justice of the highest court in the land, when he was an attorney working in the lower ones. Marshall was devoted to defending African-Americans who were wrongly accused of crimes, even though doing so frequently put him in danger.

Armed solely with his ingenious legal mind and defiant demeanor, Marshall squared off against bigotry and adversity at every turn.

Marshall tells the remarkable story of how Marshall and Friedman weathered a deeply hostile storm of fear and prejudice in search of the one weapon that supersedes all others: the truth.

Marshall’s stellar supporting cast also includes Jussie Smollett, Sophia Bush and James Cromwell. The film hits theaters October 13th, but you can get a look at its trailer now in the video above.
