“Filmmaking is famously described as ‘showing and not telling’. My favourite thing about it is that screenwriting is the art of getting a character to say something which reveals a completely different truth to the words they say. As Emma Thompson said when I had the honour of meeting her (it’s in the book!), screenwriting is the art of a character saying, ‘Pass me the butter’, when they really mean, ‘You have ruined my life.'”
