According to reports, Usher wants to play the role of Marvin Gaye in a film about the singer, having already once portrayed him in a guest appearance on US TV show 'American Dreams', which is set in the sixties. He says, "I want to be the person who tells the story of Marvin Gaye because I understand the conflict he had as a man."
Sadly for him, there's a film about Gaye already in production starring TV actor Jesse L Martin. Of course, there's nothing to stop him from making his own competing film, if he wants to, I suppose.
