A live action version of Manga's Dragonball is in the works for a August 2008 release by 20th Century Fox.
Produced by Stephen Chow
Directed by James Wong
Justin Chatwin as Goku
James Marsters as Piccolo
Emmy Rossum as Bulma
Don't know who that Justin guy is, but James Marsters rocked it on Buffy the Vampire Slayer and Angel; and Emmy Rossum is a hottie that can act.
Can't wait. Hope it turns out well.
