It's quite the business, in fact it's a $2 billion business over 130,000 acres in 23 countries.
Not surprisingly, the reviews have been positive and it is very similar to another documentary which is also well worth seeing that was shown to mark his 70th birthday, which revealed a similar view of his world, his outlook, his hopes for the planet.
How he was green before green was even a thing.
For all his trials and tribulations, you can't fault the man on service, which is why his other headline this past week has been over his fury at his two sons who appear not just to have fallen out but to have dragged the good name of the royal household into disrepute.
Harry and Meghan's simpering expose shows, tragically, an example of how generationally we have sunk to a new low.
Attributes like resilience, sacrifice and a stoic outlook have been replaced by complaint, superficiality and a wafer-thin ability to weather life. The only advantage Harry has, is he's not actually that important.
He's not the next King or the King after that. William is, and if Harry has done his brother a good turn, it is to show that he and his wife actually take their role seriously.
And the more flakey Harry and his airhead Mrs look, the more impressive William and Kate appear. And for all those that say who cares it's just royalty, that is true, but it comes with constitutional significance. The Queen is our head of state.
Britain is inextricably linked directly to us, and the Commonwealth, and as such they play a critical role in this country's history and life.
No word of course from the Queen, but one can safely assume she must be wondering why her annus horribilis years are driven almost exclusively by those of her family who simply don't get it - or care to get it. The inescapable conclusion from last night's insight, is that for some, no matter what your advantage in life, it's all about attitude. Even in the most gilded of existences, misery and woe is still at hand if you don't care to see beyond yourself.
