Yep, air gordon, I've seen it all! It was created by Dexter's Lab animator Gendy Tartakovsky. It's a good watch if you see it in one sitting because Cartoon Network showed each 10-minute episode separately. I watched the "special marathon."
*some spoiler*
Mace Windu took down a whole base, alone, using the Force and also destroyed some fighter ships. Yoda damages 3 gigantic carrier ships only by manipulating them, used the Force. hehe
Good to see that the bad-ass mechanical Sith Lord, in the cartoon who collects lighstabers of the Jedi he kills, will be in Episode 3.
I think the actual actors did the voice-overs in the cartoon.
