Wilson is proud to have been involved in creating what he calls a “generational gift” that parents like him can watch and learn from, alongside their own children.
“I think it’s got all the feels – it’s got great behaviour, it’s got great emotion, it’s got great humour, it’s got relatable parental dilemmas.
“And it has a nod and a wink towards ‘helicopter parenting’ and ‘snowplow parenting’ – all those different terms that we bandy about as to what type of parent you are.”
He’s equally pleased with having delicately explored “perhaps the most sensitive relationship that is present in the natural world” – that between a parent and their young.
To capture that, he explains, relies on “absolutely top class field work”, patiently watching and getting shots in “an observational, non-invasive way.”
“You have that extra challenge in parenting,” he says. “It’s less hard if you’re covering a hunt, as more often than not, the animals couldn’t care less whether you’re there because they’re in the zone.
“But in parenting behaviours, you’re dealing with something that’s very sensitive, and if you get it wrong, you’re stepping over a line that you shouldn’t.
“So we’re very proud of what we’ve put on screen in that way.”
During one such scene, Sir David’s famous voice is heard declaring: “Success for all parents has perhaps the greatest of consequences… It ensures the future of life on our planet.”
In other words: respect your elders.
Parenthood, which has five episodes, begins at 19:20 BST on Sunday 3 August on BBC One and iPlayer.
