“One Night in Miami” is one of those dramas with a hooky, irresistible meeting-of-the-minds premise that places four legends in a single room, all so that we can sit back and watch the verbal-philosophical fireworks fly. The movie takes place on Feb. 25, 1964, the night that Cassius Clay, at 22, won the world heavyweight championship by defeating Sonny Liston in a title bout at the Miami Beach Convention Center. To celebrate his victory, he heads over to the modest, rather shabby small suite where his friend Malcolm X is staying at the Hampton House, a motel that caters to Black celebrities. There, the two are joined by the football superstar Jim Brown and the soul legend Sam Cooke.
