7. Justin Chatwin as Goku in Dragonball Evolution (2009)
This isn't a completely different franchise that shares the same name as the immensely popular Japanese anime series. Nope, Dragonball Evolution is intended to be a straight up live-action adaptation. Ponder then, why the superbly Caucasian Justin Chatwin landed the lead role as Japanese Dragonball hero Goku? Did studio execs think his Asian-style gelled hair would be sufficient?
The lazy casting doesn't stop there eitherâ€”Chatwin's future Shameless co-star Emmy Rossum fills in as Bulma Briefs, along with James Marsters as Piccolo (he's green, so we guess that was up for grabs). Karmic justice was doled out for white-washed casting thirst, as the bid to make the leads more relatable failed and the film tanked.
