Earlier we showed you a movie Hayao Miyazaki never made, and here we can show you a piece of one that he did. The last piece, in fact, of the last movie he'll ever make, by most accounts; though the globally-beloved animation master has announced—and rescinded—his retirement before, this time he's rumored to be quitting for good.

So here we have something akin to watching Frank Lloyd Wright draw his last line, or Harley Earl shaving his last piece of clay. And it happens in a cramped-looking, low-ceilinged office lit by fluorescents, with an actual pencil and paper.

Not sure if you caught it, but the clip is significant as he changes the final meaning of the entire movie (The Wind Rises) by changing a single syllable of a single word uttered by one of the characters.This footage, by the way, is an excerpt from The Kingdom of Dreams and Madness, a documentary in which director Mami Sunada was "Granted near-unfettered access to the notoriously insular Studio Ghibli....The result is a rare 'fly on the wall' glimpse of the inner workings of one of the world's most celebrated animation studios, and an insight into the dreams, passion and singular dedication of these remarkable creators." The just-released documentary is significant in the animation community, because Miyazaki formally announced his final retirement—"This time, I mean it"—on camera.

Here's the trailer—and be warned, emotionally-invested Miyazaki fans, this is a tough watch:
