Poor Will Smith. Ali was an unplayable character.

Muhammad was truly one of the most charismatic beings to ever grace the planet. I can't think of anyone in the acting world who could have done him justice because this is the one case where the subject of a biopic actually had more originality and magnetism than Hollywood could ever dream of pumping into a fictional portrayal. Smith is a fine actor and he gave this role his best but for those of us who have seen the man himself, it doesn't measure up to the genuine article. That's not a criticism. Ali was the embodiment of human greatness.
