That's James Brown, who's not in Children of Men. Want to know the connection? You can go read my review of the movie. Sorry for the shameless plug, but after I wrote my review, I just felt like it's such an appropriate movie to mention here. It deals with political problems around the world in an intellectually and emotionally effective way. I think anyone who's reading this blog should go see it.
P.S.: That still is from a short film called Beat the Devil, and there's your hint for finding the connection without reading my review. In Beat the Devil, it is revealed that James Brown made a deal with the the Prince of Darkness many years ago, and the Devil is ready to collect. But the Godfather of Soul isn't gonna go that easily! Eternal youth will be his!
So don't be surprised if we soon find ourselves hearing about some hard-working bright young funkster...
P.P.S.: Oh sweet, Beat the Devil is no longer available for download or purchase from BMW, but it is on YouTube.
