Feb. 25, 1964, is the night screenwriter Kemp Powers dared to reimagine with his what-if conversation among Cassius Clay, Malcolm X, Sam Cooke and Jim Brown. He paints a picture capturing the four, who were all friends in real life, just before each man’s life takes a significant turn. For Clay (Eli Goree), it was just before joining the Nation of Islam and becoming Muhammad Ali even as X (Kingsley Ben-Adir) was departing the organization. Cooke (Leslie Odom Jr.) was realizing the true power of his voice, and Brown (Aldis Hodge) was planning his transition from the NFL to Hollywood.
