I believe in tension and release, in that if you stay in the the same tone and mode and intensity for too long, it actually becomes monotonous. When you change up your pace or your humour level, then the release is welcome. … I believe that's my biggest job: tone control, and maintaining enough unity so that it all feels like one movie and all the scenes belong together, and yet diversity so that emotional and narrative interest is maintained.
