The full quote if anyone's interested....
Now here's a director talking sense!
You mentioned these six minutes of new scenes. Are you one of these guys like George Lucas who likes to go back and tinker with their old films?
I’m not into revision. I think every film should be exactly as it was executed in the moment. We’re not changing the rest of the film, we’re just dropping these scenes in. I actually don’t believe…like when George went back and put new creatures into the original Star Wars, I find that disturbing. It’s a revision of history. That bothers me. I certainly wouldn’t go back and do that to any of my films. A film I made in 1984, it’s what it is. It’s a creature of its time. But with these new scenes we’re adding, I think people certainly had an appetite for more Avatar than we gave them. Nobody complained about it being too long. The scenes we’re putting back are righteous scenes, they’re not Jake sitting around talking about his childhood.
