8. 3D Or Not 3D?

Up is Pixar’s first attempt to make a story that works in the digital 3D style, and while the company appears to be embracing the technology wholesale - retro-fitting their back catalogue, including Toy Story, with the new tech - the team were wary of gimmickry...

“I think it adds a sort of a depth but it was important to not have the technology detract from the story,” says Docter.

“Some films... do a lot of ooga-booga, you know, reaching out. And for this type of film, we're trying very hard to make it as subtle as possible. It adds to the richness, to the depth of the environments.

“You walk through the jungle, and you can see all of these layers going back."

“I think the flying as well,” adds Rivera. “They go up in the sky, and look through the clouds... we're enhancing the 3D by using the screen as a window, looking in, as opposed to breaking things out into the cinema.

“So it's sort of treating it like theatre, where you're looking through at the stage and it really gives the whole thing a nice depth.”
