Charlie Hunnan has exited the role of Christian Grey in Fifty Shades of Grey. Fan reaction seems mixed, even though nearly everyone hated the idea at first. Charlie wasn't a bad choice at all in my opinion. He was really growing on me so much that when the news of his departure broke, I was actually disappointed. Below you will find Universal's official statement as to why Charlie left the the project.
The filmmakers of Fifty Shades Of Grey and Charlie Hunnam have agreed to find another male lead given Hunnam’s immersive TV schedule which is not allowing him time to adequately prepare for the role of Christian Grey.
There has been a lot of doubt as to whether or not that statement is really true and if that was, in fact, the actual reasoning behind the decision. In the mean time, there has been a lot of speculation as to the "real" reason why Charlie departed.
