This idea of leaving a great deal of open space for the spectator is not limited to the end of the film. I have always had the desire to have the kind of film where I have created a great deal of spaces inside the film, where, like a puzzle, the spectator has to fill in the spaces -- I like to create those kinds of spaces where the personalities in the film begin to engage with one another and at the same time leave room for their spectator to connect them in a way in which they would like to see them connected. Some people like their movies to be perfect as they describe it, but I don't seek that kind of perfection. To me perfection is defined by how much the spectator can engage in the movie, and so a good movie is one that involves the spectator as a part of it and not as a captive person.
