I give the spectator the possibility of participating. The audience completes the film by thinking about it; those who watch must not be just consumers ingesting spoon-fed images.
An artist is someone who should raise questions rather than give answers. I have no message.
At its best, film should be like a ski jump. It should give the viewer the option of taking flight, while the act of jumping is left up to him.
Films that are entertainments give simple answers but I think that's ultimately more cynical, as it denies the viewer room to think. If there are more answers at the end, then surely it is a richer experience.
Usually, when making a film, the surprises are negative surprises. You don't get what you wanted or what you hoped for. The only nice surprises are those that are offered to you by actors when they offer you these gifts, when they are better and give you more than what you had originally conceived. That doesn't happen every day on set, but if it happens a couple of times in the course of making a film, you can consider yourself very lucky.
