"I like to think of myself as the ultimate anti-postmodernist post-modernist. Notwithstanding the unusual narrative or visual devices that appear in many of the films, what have kept me going for the three years of investigating [for , was the belief that there answers to questions such as, Adams did it, didn't he? Or Harris did it, didn't he? That it's not just up for grabs. Today, I believe there's a kind of frisson of ambiguity. People think that ambiguity is somehow wonderful in its own right, an excuse for failing to investigate. What can I say? I think this view is wrong. At best, misguided. Maybe even reprehensible."
