2. Zachary Quinto
We can pretty much take it as a given that we will see another Jedi turn to the Dark Side in the new trilogy. After all, every Jedi needs a Sith to defeat. Theres no one I would rather watch leaving the Light Side behind to become a Sith Lord than Zachary Quinto. As Heroes' Sylar, weve seen Quinto use telekinesis in completely new and terrifying ways. His knack for menacing looks would be the icing on the cake. Just imagine him with a black cloak and shiny red lightsaber. Hes got Sith written all over him.
