ONE NIGHT IN MIAMI: 4 STARS We ll never know exactly what was said between Cassius Clay, Nation of Islam leader Malcolm X, soul singer Sam Cooke, and football superstar Jim Brown behind closed doors in a Miami hotel room on February 25, 1964, but a new film by Oscar winner Regina King in her directorial debut offers up a fascinating what-if scenario. Going into the boxing ring on that night against heavyweight champion Sonny Liston, Cassius Clay (Halifax-born Eli Goree), who had not yet officially changed his name to Muhammad Ali, was a 7-to-1 underdog. When the fight was over, Clay was the youngest boxer to ever grab a title from a reigning heavyweight champion.
