(on a side note...wasn't Goku's real name Kakkarot? I know it wasn't Carrot.)

I suppose it was natural for them to play the asian angle especially for this movie, but i still thinks that the main reason they cast Justin Chatwin as Goku was to appeal to the masses.
You're probably right on this. =/ (reminds me of Chun Li. I'm guessing they cast Kristin because she's popular due to Smallville)

It might be one of those LET'S CAST A GOODLOOKING GUY SO WE WIN things. Where they think fangirls/boys will come for the eye candy,
