User blog comment:CorbeauKarasu/Why there will never be an FMA live action film by Russinmy/@comment-1299622-20121202072225

They'll never relinquish control. They're respecting Arakawa's wish for the Fullmetal Alchemist story to basically stay rested the way it is (which is quite timeless if I may say so myself), and no disrespect to Russ, but especially after what happened with Shyamalan's The Last Airbender and James Wong's Dragonball Evolution, there's no way they're breaking that to sanction any Western-produced live action film release.

Even another anime film can't be promised, though I'd agree with the assertion that those are basically all that's left not to rule out.
