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 want to explore new ideas and put myself in a place where I can finish a project that is more unusual or that doesn't seem doable.

Every movie I do is challenging for me. There is some element of imaginative that you wouldn't have in a typical movie.

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.

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 like to use a bit of chaos when I shoot. I think it may be something from the way I shot my first film - I was very scared, of course, and I prepared everything, I wanted to make sure that the characters did the right thing at the right time on the storyboard. But then I realised that in life, there is so much more than what you can predict or write in advance, that when you shoot the story, it's good to leave some gaps where you lose control. I think this combination of chaos and organisation gives a kind of quality.

I read about some movie where they did everything on blue screen, and the actors were not even connecting to each other.
