I'm still under the impression that, whether we want it or not, Viz will try to get Naruto made into a live-action film if Dragon Ball does decently.
Death Note, I can seriously see happening. Really, we've seen it adapted into live-action THRICE (okay, twice, the third time just being a spin-off movie for L fangirls), and knowing how most Japanese WB films in that genre tend to get adapted at some point, it's only a matter of time.
I'd love to see how Hollywood would handle a FMA or Soul Eater adaption, but they'd probably kill it with Disney's pool of child/teen actors.
But, if anything, I stand by the comment I made a while back: ONE PIECE SHOULD NEVER BECOME A LIVE-ACTION MOVIE.
