Justin Chatwin (Goku) - It's been reported that he will be the ONLY cast member who will NOT be wearing a wig. Apparently Mr. Wong feels his hair looks enough like Goku's on its own. I beg to differ. Also, does this guy look anything like Goku? You be the judge. Oh and yes, the photo that is linked is actually Justin Chatwin on the set of Dragonball. So yes, that's actually the hairdo they're supposedly going with for Goku. You may cry like a baby now.
Emmy Rossum (Bulma) - Yes, she will be wearing a blue wig. Is Bulma really supposed to be THAT hot? And can they really cast someone that hot as Bulma and NOT put in the infamous Goku stealing Bulma's panties before she flashes Master Roshi scene?
James Marsters (King Piccolo) - Yes he will be painted green. As of yet, there is no confirmation on his antennae, but there is speculation that they could be CG'd in later. Honestly, this is one of only two casting choices I completely agree with. He was a badass and supremely evil as Spike in Buffy: The Vampire Slayer. To be honest, James struck me more of a Piccolo type and not a King Piccolo type, but I still feel he'll do the character justice. Hopefully they'll bring him back to play Piccolo in Dragonball Z.
Chow Yun-Fat (Master Roshi) - WTF?! I love him as an actor and all, but seriously, Master Roshi?! Are they smoking pot over there?! They cast the Asian actor with the least amount of martial arts experience to play a martial arts master... >.> Also, I have to question whether he has a high enough proficiency with the English Language to make Master Roshi as funny and outrageously perverted as he should be. Of all the cast members, he should be watched the closest, in my opinion. Should he actually nail the Master Roshi character, his popularity will sky rocket and his career will move to a level beyond his imagination.
