Josh Gad is headed to court. He'll join Chadwick Boseman in Marshall, a biopic of the first African-American Supreme Court Justice, Thurgood Marshall. Reginald Hudlin is directing the film which centers on one of Marshall's most prominet cases, that of black chauffeur Joseph Spell against his wealthy socialite employer in a sexual assault and attempted murder trial that quickly became tabloid fodder. The NAACP assigned Marshall to the case at a time when they were badly in need of a high-profile victory and facing a storm of fear and prejudice. Gad will play Sam Friedman, a Jewish insurance lawyer who teams with Marshall in hopes of winning his first case. [Deadline]
