There are times when our national passion for cutting people down to size is a little tiring. I left Brett Morgean’s new documentary about Jane Goodall, the chimpanzee expert, in a rare flush of excited enthusiasm. ‘You’ve got to see it!’ I said to everyone. Most replied along these lines: ‘Goodall, didn’t she turn out to be a fraud?’ Or: ‘Wasn’t it all Leakey’s work she took credit for?’

‘Yeah, what’s with that?’ says Brett Morgen hunched over his toast in a very hipster Soho hotel.
