The doctor is in...a galaxy far, far away. David Tennant, star of Doctor Who, will guest star on this weekend's episode of Star Wars: The Clone Wars, "A Test of Strength," in a role that is a major addition to the Star Wars mythos: Huyang, an ancient, wise droid who oversees the building of lightsabers by Jedi younglings.

"My wife was the one who got me watching Doctor Who," says The Clone Wars' supervising director Dave Filoni, "and I am really glad she did. I remember thinking that the series (Doctor Who) had many of the same production challenges that we do on The Clone Wars -- creating galactic scale adventures and planets with strange life forms." But it was more than an affinity for Doctor Who that led Filoni to Tennant for such a crucial part in "A Test of Strength."

"As a fan that has the privilege of playing in the Star Wars galaxy, I am always on the lookout for others who appreciate, and would enjoy, an opportunity to go on an adventure in George's galaxy far, far away. When I heard the Doctor himself, David Tennant, was a fan of Star Wars, I knew I had to find a way to get in contact with him to see if he would perform on The Clone Wars. The result was Huyang...I thought David was perfect for the part and he did not disappoint. He delivered a performance which impressed even the Master himself, George Lucas."

Check out a clip of Huyang in this video, and be sure to watch "A Test of Strength" on Cartoon Network this Saturday, November 10, at 9:30 a.m.
