You need philosophy. It sounds a little pompous but I think when you direct a film, the only way to find a response to the questions you keep asking yourself is to have a philosophy.

I'm attracted to working with comedians because they don't have that stars' idea of what a hero should be. The downside is they're always addressing the camera too much.

Orange is an underrated color, it's the second most underrated color after yellow.

Sometimes it's interesting to see something that you're not used to seeing, which is the main ingredient of life, and it's removed from the usual entertainment. I think it's important to give the opportunity to people to witness the life of somebody who was not public.

I think animation is a very truthful way to express your thoughts, because the process is very direct. That's what I've always liked about animation, particularly abstract animation. You go from the idea to execution, straight from your brain. It's like when you hear someone playing an instrument, and you feel the direct connection between the instrument and his brain, because the instrument becomes an extension of his arms and fingers. It's like a scanner of the brain and thought process that you can watch, or hear.

I like actors who just are who they are, with a little bit of qualification to adapt to their character. But mostly they just use their own personality to embody the character.

My grandfather lived across the garden from us, and in his attic he had a lot of radios, appliances and inventions that he had made over 50 years, such as a keyboard called a clavioline, which can be heard on some Beatles songs - it was popular in the 60s. So we had all that at home.
