Starwars.com updates with an interview highlighting Samuel L. Jackson as Mace Windu. Here's a clip of the article that originally appeared in the SW Insider a few months ago:

You just finished a fight rehearsal with Nick Gillard. Was that fun?

Nick is the man. This is my second go-round with Nick--he also did Shaft. Now he's doing lightsaber battles for us all, and a lot of Kendo stuff. I guess that, because I'm such a fan of Japanese samurai movies and I've watched a lot of Kendo fights, I'm doing pretty well at it. It's basically a lot more footwork than I thought. For the sword stuff, getting the feet right and getting the steps so you can actually do it right--it's a lot like dance choreography. The feet have to be right so that the strikes look correct.

He's put together a pretty exciting and incredible fight for me. And since I'm supposedly the second baddest person in the universe, I'm pretty efficient. I don't do a lot of fancy sword-twirling or anything. I dispense people pretty quickly, use as little energy as possible. But I'm pretty bad.

Did you have to train for this film?

When I was first on the set, about a month before, Nick showed me certain things to work on when I got home. I've been doing it very intensely for the past two days--so I'll be ready by next week when it's time.

At the MTV Movie Awards, George announced that he thought you were going to be up on that stage soon accepting for the best fight sequence.

Yeah he did, didn't he? Put a lot of pressure on me to do some major butt-kicking here. So hopefully that'll happen.
