I think, if allowed, 3D is a new film language. I can have more adventure exploring a new media, that's very exciting. 2D we know most of it, things haven't changed for decades; it's the same principles, so 3D's more exciting.

It was nerve-wracking [to unleash 'Life of Pi' to the world]. The first show to the journalists, that was the first one, so I was very uptight. Then I felt okay about the reception because we did a press conference with good and friendly questions, although people looked serious. So really, after the show you went to - the premiere - that reception tells me I think the movie worked, so that was a relief. I started to feel deflated.

When I grew up, in Taiwan, the Korean War was seen as a good war, where America protected Asia. It was sort of an extension of World War II. And it was, of course, the peak of the Cold War.
