StarWars.com has posted an excerpt of an interview from The Star Wars Insider #113 with The Clone Wars producer Cary Silver, dealing with George Lucas' involvement in the production of the series.:

"How hands-on is George Lucas?

Far more than anybody realizes. He's very involved in the crafting of the stories and the whole script process. He's also involved throughout the production in terms of seeing artwork, providing reference, ideas, and concepts for designs. He personally goes through every episode in the production phase as well as the final edits of the episodes once they're in full color.

George has his own ideas about where the show should go and where it should be and that pushes us into directions unknown. The reason why he's been such an amazing, innovative filmmaker all these years is because he's not bound by the limits of the craft of film-making today, or the levels of quality that can be readily achieved. He's continually light years ahead of the curve, and that creates a great deal of production challenges to figure out a way to be true to that. I have to say that I think we've struck a good balance, and I know he's very happy with the show and the way it's looking. It's incredible working with him. To sit in script sessions with George, or to sit in edit sessions, is an absolute master-class in filmmaking."
