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.

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.
