‘One Night in Miami’ review: Malcolm X, Cassius Clay, Sam Cooke and Jim Brown play the king’s gambits

Meantime, Brown and Clay — “gladiators,” as Brown says, bitterly, battling on their respective battlefields — find themselves at two different crossroads. Brown has just completed his first movie, a western (unnamed, but it’s “Rio Conchos”), and eyes a career change. Clay is played by Eli Goree, a ringer vocally for the man who would become Muhammad Ali. He may be on top of his world at 22, but as Clay learns Malcolm’s plans … well, that’s one of the late-stage reveals in “One Night in Miami.”
