Well, that would be another Batman lol. Not Naruto.
Seriously, I love Nolan movies and Dark knight but Naruto just won't go along with a dark theme to me. Kishi never gave that edge to the series really.
Frankly, if they wanna do it big, I'm afraid it might turn out to be disastrous.
What I'd suggest if they really wanna capitalize on Naruto popularity and make something that turns out good and sincere towards Naruto fans, then they should take good talented unknown Japanese actors.
We already saw the result of taking mix of Canadian-American actors in DBE :sy:
Something like this would be awesome but with a good extended plot.
Zabuza-Haku Arc or Pain Invasion Arc are two arcs that could translate into good movies in my eyes. Though I'd prefer to see Orochimaru as villain if someday there were to be a Live Action movie.
