Don't worry, though, he hasn't become a Cyberman. Tennant voices the character Huyang, an ancient droid who helps young Jedi build their first lightsabers. He first appears in "A Test of Strength," airing at 8:30 a.m. CT Nov. 10 on Cartoon Network. Tennant and Huyang stick around for the following two episodes, "Bound for Rescue" and "A Necessary Strength."
"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,'" supervising director Dave Filoni said in a press release. "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."
A sub plot in the episode involves the bandit Hondo, who wants to intercept a ship of Jedi younglings in order to take their time crystals, which are used to power lightsabers. Any "Doctor Who" will recognize the happy coincidence of having Tennant--who played the Time Lord--in the episode.
Tennant stars in the upcoming BBC America series "Spies of Warsaw," which begins in early 2013. He'll definitely look more like himself in that series.
Here's more trivia about "A Test of Stength:"
- Petro's lightsaber training maneuver--the Whirlwind of Destiny--was created a young fan as part of the Join the Jedi contest sponsored by Hasbro. The winning entry was animated into the show.
- The training remotes seen aboard the Crucible are the same design as the one seen aboard the Millennium Falcon in "Episode IV" and in the Jedi Temple youngling training verandah in "Episode II."
