For me, architects and film directors operate similarly. They are practical. As an architect, you know what you want in the conception of a space - but you still need a lot of people to help you out. You need an engineer, interior architects. But a film is the same - you have all these elements. But in terms of concept, it's always about time. When you approach a building, you need time to go from point A to B. Buildings are designed as a journey and films are the same, you have an opening that you come through, an angle you follow, maybe a disruption in space.
