Will Smith floats and stings as the boxing legend known as "the Greatest" in Michael Mann's electrifying biodrama. From the then-Cassius Clay's first heavyweight win in 1964 to his 1974 "Rumble in the Jungle" victory over George Foreman, the film follows the cocky and controversial Ali's conversion to Islam and friendship with Malcolm X, his stormy marriages, and his refusal to serve in the Army that led to public scorn and a three-year exile from the ring. With Jamie Foxx, Ron Silver, Jada Pinkett Smith. 157 min. Widescreen (Enhanced); Soundtracks: English Dolby Digital 5.1, French Dolby Digital stereo; Subtitles: English, Spanish, French; theatrical trailers.
