Director's ideas
On the origins of the movie, director Mamoru Oshii says he didn't envision it solely as a sequel to Ghost in the Shell. He said, "I had a dozen ideas, linked to my views on life, my philosophy, that I wanted to include in this film ... I attacked Innocence as a technical challenge; I wanted to go beyond typical animation limits, answer personal questions and at the same time appeal to filmgoers." During production, the first decision Oshii made was to not make Motoko Kusanagi the main character and instead make it a story about someone searching for her. Oshii chose to make the movie have a different tone and feel from the original.[5]
Oshii traveled the world in order to find inspirations for the film. Oshii based the appearance on the dolls created by Hans Bellmer he saw at the International Center of Photography in New York.[6] He credited Jean-Luc Godard for the idea of including quotes by other authors: "[The texts] ... give a certain richness to cinema because the visual is not all there is. Thanks to Godard, the spectator can concoct his own interpretation ... The image associated with the text is a unifying act that aims at renewing cinema, that let's [sic] it take to new dimensions."
Oshii noted his attention to detail might be particularly Japanese: "I get absorbed in the finer points – like what the back of a bottle label looks like when you see it through the glass [demonstrates with a bottle of mineral water]. That's very Japanese, I suppose. I want people to go back to the film again and again to pick up things they missed the first time." Describing the overall look, the director said, "The film is set in the future, but it's looking at present-day society. And as I said, there's an autobiographical element as well. I'm looking back at some of the things I liked as a child — the 1950s cars and so on. Basically, I wanted to create a different world — not a future world."
The dog Gabriel, looking once more like the only "real" being, makes a key appearance, as in many of Oshii's movies. A scene with Batou feeding his dog is echoed in Ash in Avalon (2001). He explained the reason why all his films feature a basset hound—his companion in real life: "This body you see before you is an empty shell. The dog represents my body. Human beings can be free only if they free themselves from their bodies. When I am playing around with my dog, I forget that I am a human being, and it's only then that I feel free."
As for the state of art and animation, Oshii had this to say:
"I think that Hollywood is relying more and more on 3D imaging like that of Shrek. The strength behind Japanese animation is based in the designer's pencil. Even if he mixes 2D, 3D, and computer graphics, the foundation is still 2D. Only doing 3D does not interest me."
On the overall message of the film, the director said "This movie ... concludes that all forms of life – humans, animals and robots – are equal. In this day and age when everything is uncertain, we should all think about what to value in life and how to coexist with others." On his narrative intentions Oshii comments: "I had a bigger budget than for Ghost in the Shell. I also had more time to prepare it. Yet despite the economic leeway, abundant details and orientations, it was still important to tell an intimate story."
