Galactic-Voyage.com is reporting that Christopher Lee has lended his vocal talents to his character of Count Dooku for The Clone Wars movie. This comes from the message boards at the Official Christopher Lee website. One of the message board members had inquired about it and an Administrator answered with the following: "Mr. Lee has recorded the voice of Count Dooku for this movie a couple of months ago. It was however, the first time he had to lip synch to a character because they had produced the animation before recording his voice."
Very cool news! Who knows what other vocal surprises we have in store for us as the release date gets closer. We'll let you know as soon as we hear something official from Lucasfilm.
Big thanks to "JediPower" for the heads up!
UPDATE:Lucasfilm could not confirm the news above at this time...but they certainly didn't deny it either :)
