A new James Brown documentary produced by Sir Mick Jagger and directed by Alex Gibney is set to be broadcast on America's HBO cable channel later this month (Oct14). Mr. Dynamite: The Rise of James Brown, which was made in co-operation with the late superstar's estate, will feature previously-unseen footage of the music icon. It is Jagger's second Brown project - he also helped to bring his life story to the big screen with the summer (14) release of biopic Get On Up, which featured Chadwick Boseman as the Godfather of Soul.
