Even in the early '90s, I was already starting to mix professional actors with non-actors. I always enjoyed working with non-professionals, because their performances are very natural and unaffected.

In my films, I like to use the same actors again and again, so I know them really well and can bring their unique personalities into the process. However, as a director, I have strict control over the way they express their personalities. I don't want them to go beyond what I need from them, but I also don't want them to underplay. So I modulate their performances very closely, within a certain range of expression.

For me, water means a lot of things. It's my belief that human beings are just like plants. They can't live without water or they'll dry up. Human beings, without love or other nourishment, also dry up. The more water you see in my movies, the more the characters need to fill a gap in their lives, to get hydrated again.

Ever since I've become a filmmaker, I'm traveling the world a lot. I feel like I'm a citizen of the world, yet there's no single place that I can put my roots down and call home. I don't own anything. I'm not a homeowner. I've always rented and never stayed in one place for long. Almost every time I rent a place, I have some sort of water leakage or flooding. Whenever that happens, I just move somewhere else. Even when I moved to Paris, my apartment started leaking after a month. Maybe the leaking is just part of my life, doomed to follow me around.
