8. Count Dooku
Yet another evil Jedi Master that George Lucas decided to cast was classic horror film actor, the great Christopher Lee, playing Count Dooku. The Count trained some of the most fearsome fiends Star Wars has ever seen, including General Grievous and Asajj Ventress. Many speculate that with the combination of his own actions and those he molded, he is more responsible for more Jedi deaths than nearly any villain within the series.
