Notorious

Getting pretty sick of this promo checking out vh1 documentaries on my daddy's TiVo. It raises some questions, though, as I'm not sure about the unknown lead. When somebody is playing a huge popcult icon I always thought sounded rather stupid, is he a great actor or a poor actor when I see the trailer for the biopic and I think he sounds rather stupid? Let's figure this out just from the ad, as I'm not planning on seeing this move in the theatre!
