Artists should not be involved in recycling ideas or existing categories, or restating already established categories. A real artist should understand and express life, without any preconceived notions or predetermined categories of perception. Some of your more recent films have been science fiction works. The only limit is your own creativity. It is time, however, to explore science fiction beyond the gadgetry and new ways of killing.
Science fiction has a much greater scope, and that is the exploration of the human being.
We have explored this planet and others but we have yet to seriously explore the mind. This is a whole new territory. It is difficult, of course, but this has always been the case. I suppose as an artist I treat the difficulties as part of the package. Even in the most advanced societies there is no unhindered expression.
