The Doctor is learning the ways of the Force. Actually, he’ll be teaching the ways of the Force to a group of Jedi younglings in Saturday’s episode of Star Wars: The Clone Wars. David Tennant will voice Huyang, an ancient droid who specializes in the construction of lightsabers. “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 Star Wars: The Clone Wars,” said Dave Filoni, the cartoon’s supervising director. “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.”
