The current issue of Starlog, has an interview with Mr Lee.
Starlog: After Rings, you moved on to another highly anticipated genre film, Star Wars: Episode II: Attack of the Clones. What was that transition like for you?
Mr Lee: I saw the fifth film for the first time last night on television - The Empire Strikes Back, the one in which Darth Vader tells Luke Skywalker he's his father. I had never seen it. Concerning my appearance in the new Star Wars movie, I'm under a confidentiality agreement and can't say much at all - anything, in fact. I don't even know if I'm allowed to say my character's name yet, though it's all over the Internet. You surely know who's in it, and you've probbaly seen the trailers by now, but all I can say about it is that George Lucas was an ideal director to work with. There was no fuss. He was completely calm and easygoing. Again, you could have fun, but the performance - when he called for action - had to be believable. With Star Wars, you're dealing with an audience that numbers in the millions, and they are all over the world. All of these people are anxiously waiting for it to come out in May, and I'm anxious to see it as well. After all, I'm only familiar with the scenes I did.
Starlog:Your friend Peter Cushing starred in the first Star Wars. Did he ever speak to you about his time on that film?
Mr Lee: No, he didn't. I remember that years and years ago I asked him, "What on Earth is a Grand Moff Tarkin?" And he said, "Well, I'm not quite sure, my dear fellow." I don't think he ever asked George! (Laughs) Peter knew he was the villain of the piece, or one of them, and that was enough for him.
