This movie could be hotter than anyone bargained for. Recently confirmed Fifty Shades of Grey star Charlie Hunnam said on Saturday that he and his costar are definitely going to work well together. "As soon as we got in the room reading with Dakota [Johnson], I knew I definitely wanted to do it, because there was a tangible chemistry between us," he said. Don't expect too many offscreen sparks, though: Hunnam's taken. But don't worry, she's supportive! The future Christian Grey also said that his girlfriend loves all three Fifty Shades books and even persuaded him to take on the racy role. Method acting, anyone?
