no offense to the Kid, but he's been extremely optimistic about this movie. i think he was exaggerating when he said that Chatwin is an ardent fan. the only thing we've seen Chatwin give any kind of interview was when they were doing the launch party in Mexico when he was surrounded by a bunch of people with recording devices in his face. he mentioned how (almost verbatim) Goku is an important character to get right because he's in a cartoon that a lot of kids watch.
the movie is still a year away, so i wouldn't expect any of the actors or actresses to start promoting or talking about it...but James Marsters is the only one that makes appearances that make it into the net. he's the only one doing interviews that gets the fans pumped up. i'm not saying that the rest of the crew aren't fans and i'm sure if you'd ask them, they'd say they were.......but actions speak louder than words and Marsters is the only one, so far, proving to us that he is indeed a fan of Dragon Ball.
