For the second week in a row, "Fifty Shades of Grey" is dominating the competition on Movie Power Rankings. With the departure of Charlie Hunnam from the upcoming big screen adaptation of E.L. James' steamy S&M story, Universal is on the lookout for some new blood. Among the many names reportedly being considered to play Christian Grey is "True Blood's" Alexander Skarsgard. Other rumors have Jamie Dornan ("Once Upon a Time"), Theo James ("Underworld: Awakening"), and Christian Cooke (2013's "Romeo and Juliet") trying on the infamous necktie. Whoever is cast, the studio had better hurry up and decide -- summer 2014 is not that far away.
