Muhammad Ali was the first great sports figure created by the television age. Everybody knows his story. So instead of trying to retell that story via a conventional biopic, “Ali” (2001) just kind of does its own thing. It’s a cross between an art film and a faux documentary. It’s fascinating, because, I mean, you know the real story, but you never know when the movie is going to stick to reality or just start freelancing a non-linear rearrangement of somewhat actual events. Best of all, Will Smith’s supporting cast is an awesome combination of minimalist and scenery chewing performances.
