I don't have incredible knowledge about films or of filmmaking history; I'm not that kind of person.

My mother loves me and everything goes well. I have no conflict with her, so that's not dramatic.

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.

So it [3D] is something I'm still learning, it's fresh, so if the budget allows I'll do it again and just see how far it goes because it's the frontier, it's more interesting. It's still expensive, the projection system can be annoying sometimes, it's not really regulated or perfected yet, so it's still expensive. If I do a lower budget I'll just do 2D, but if the budget allows I think I'll try 3D.

I feel like all of my characters now take this congested situation, they clash, and from there you purge yourself.

I look at American movies, the big muscles, and try to apply that to Chinese film-making.

Summer blockbusters are very expensive to make. They have things that have to be expensive, such as 600 effects shots or CG characters that have to go a certain way, or a film design that is different but expensive.
