NEW YORK (AP) - So far, so good for the man fingered to be the new leading man in "Fifty Shades of Grey." Jamie Dornan has been cast as Christian Grey - and so far social media reaction to his casting has been generally positive. That's a contrast to what happened when Charlie Hunnam landed the role. He ended up unhitching himself from the project recently. Dornan will play opposite female lead Dakota Johnson in the movie adaptation of E L James' best-selling erotic novel. The movie is to start shooting next month - with a release set for next August.
