They pick the wrong actor!
Ok, love me some JB I attend his concerts in the 70's when he was in his prime. He had style and great showmanship that was felt in the audience. His show's was a three hour marathon of music and dance at it's best, that keep you on your feet. It takes a great musician and ton of charisma to do that night after night as JB did for his audience.
I'm telling you this actor didn't hold me for two minute of a promo he is uninspiring. He was just reading lines there was no James Brown to be found in this performance. He will be the reason this movie will sink. Look at the movie "Ray" I love RC he was one of the greats. His music and talent was universally admired, but it was Jamie's performance that made that movie bio spectacular. This actor is good but not special he was flat in "42". I think he will be just okay in this as well.
