Who would you choose to act as Duke in a Live action movie?

As I was watching some of the anime, I was thinking that this entire series is really accessible and would be well suited for a live action film. If hollywood made one, who do you think would be a good actor to play him?

Personally, I think the Rock would actually be pretty good. For one thing, mofo is buff as hell. Also, he's got the ethnicity unknown but with some asian in there down pretty good. The only downside is that he's a pretty jovial fellow, and I don't think he could play the character as stern and taciturn as needed. Still, food for thought.

The payoff for slogging through an hour of boring is never worth it.
