this was originally posted in the gripes/concerns thread but i put a lot of thought and effort into the post and since it also has to do with Goku and Chatwin i'm reposting it here. you can reply/discuss if you'd like...
apart from him being skinny, i honestly feel he's wrong for the role. when he was first announced as Goku i can remember my first thought being "wtf, really???" because it was a casting so far removed from what i was expecting regardless of ethnicity. i honestly don't have a problem with them casting a white actor for the role so long as they get a qualified or inspired actor. not necessarily someone who has martial arts experience but at least someone with charisma. even with Chatwin's thin frame, i wouldn't mind him as Goku if he were charismatic but he simply isn't.
there's really nothing about him that makes him stand out from the typical white suburban male. i've watched War of the Worlds, Invisible, and the episode of Lost that he starred in and there's nothing about him that makes me like HIM, in particular. he pretty much annoyed me in War of the Worlds and bored me in the Invisible. when i saw those movies, there was nothing that he did that made me go "i can't imagine any other actor in his place"...and that's something that i wanted for Goku even if whoever's cast doesn't match my ideal Goku, physically.
i remember watching Invisible and thinking to myself "does this guy's face ever change?" he didn't really do much in the Invisible besides a lot of shouting and pointing but i won't hold that against him. i understand that the script required him to do that but that's really all he did. he didn't convey true emotion, or if he did...his face didn't express it. when his mom was crying over his death, it was supposed to be an emotional, tear-jerking moment, but it fell flat because Chatwin just kinda sat their unphased when a better actor with little more initiative would have taken it upon himself to run with it and do something a little extra. i wasn't expecting an oscar-winning or stage actor, but i definitely wasn't expecting a flavor-of-the-month actor either.
on top of that, i feel he doesn't really understand or care for the material. there was a short video of him conducting a public interview in Mexico at an event for kicking off the filming of Dragonball. in the very brief interview, he kept insinuating that Dragon Ball Z is a kids cartoon and that a lot of kids watch the cartoon. then he said he hopes that he can play the character "good". his remarks about Dragon Ball being a kid cartoon (instead of an anime) is a possible indication that he only thinks kids watch the cartoon or that it's a children's cartoon and him saying that he hopes he can play Goku "good" (not "well") is an indication that he doesn't have a strong grasp on how the character should be portrayed or that he doesn't have much confidence that he can deliver. mind you, the lady asking him questions spoke broken English and he had close to 20 microphones circled around his head but this was at a public event that he should have been prepared for. even if he was nervous, his words are still clues as to how he feels about the project.
in short, i feel they picked a less than stellar "actor" for Goku. i don't care that he's white or that he doesn't have muscles like Hugh Jackman. i just care that he doesn't seem to be the type of actor that would take this role seriously. in the end, i can't blame him because it seems like the only people who are taking this movie seriously in the first place are not the people involved with the film, but the fans.
