Yup, I really want to see what Lord Piccolo and Roshi will look like. Good thing is that we are closer to a teaser trailer now.
About Chatwin, his hair looks good for a real live action movie. His body is ok, remember Goku wasnt buffed in his fight with King Piccolo (yes he was a kid I know) and Piccolo Jr. So its fine. Although I really really hope he trains and bulk up for the sequels. Thats a MUST. I mean, im not saying he should be exactly like Goku was in his fight against Vegeta (all SUPER strong like a body builder), but he (Chatwin) at least should look strong.
