I saw this move this weekend with a friend and it was Awesome! Unfortunately it's an indie film, so you have to really search in your area to see when and if its showing. I know in NYC it is showing in only 2 theaters. For those of you who don't know what this movie is about I'll give a quick highlight.
This documentary chronicles the time leading up to the famous Ali-Foreman fight "Rumble in the Jungle". It focuses on the 3 days music festival that was put together by Don King and a few other cats leading up to the fight. The film give good insight into the thoughts and feelings and the excitement of the various bands as they journeyed to Zaire the days before the huge festival. The film shows performances by the Spinners, B.B. King, Celia Cruz, James Brown and a few other surprises that I'm sure you will enjoy. If you are able id recommend seeing this film at the theater. If not be sure to but it on DVD once its released.
