Making a movie about an iconic figure like Ali and how does Mann open the film? With Sam f'n Cooke. Doesn't get any cooler. What follows is a 10 minute opening sequence among the most impressive filmmaking of the last decade. Yeah, the Ali story/characters are a bit condensed and simplified, but Mann and Lubezki are amazing the whole way. Perhaps not compellingly dramatic, but this is filmmaking of the highest order.
