I am so picky about what films I get myself into because it's such an explosion of energy and commitment once you get in there, you destroy your life until you deliver these films. I never want to be in the position of making films that won't be a great use of 90 minutes of someone's life.

Supermarkets didn't even want to talk to me about how much food they were wasting. I'd been round the back. I'd seen bins full of food being locked and then trucked off to landfill sites, and I thought, surely there is something more sensible to do with food than waste it.
