When did TV documentaries become all about celebrities and 'being' and stop being about people actually doing something?

My friend and I used to be fans of a big documentary festival until about a decade ago. After yet more films about a boy wearing mascara, or a girl holding a Kalashnikov, we walked out after a screening and she said, "It’s all about being. When did people stop doing stuff?"

To be fair, documentaries remain a crucial platform for investigative journalism, but when it comes to our TV screens, my friend was right. We aren’t short of what TV commissioners call "factual entertainment", but it feels like a million variations on a single premise: two celebrities in a car swapping their "stories", between stops where they buy a house and a surprisingly valuable bit of art.

Or, if it's Channel 4, an intentionally provocative session with some kind of sex practitioner. If an expert is called upon, it’s to answer the questions of yet another celebrity. Where are the people doing stuff?

It wasn’t always this way. I grew up watching people like Keith Floyd, Ann Ladbury and Fred Dibnah and their infectious enthusiasms for, respectively, cooking without a recipe (but with a glass of red), cutting sewing patterns and demolishing chimneys. They were all doing it anyway; fame came through their passions, not the other way round.

The word "geek" – which just means a deep, tireless interest in a subject, often niche – has been given a bad rap, associated with a bad haircut and passion for planes over personal grooming. Well, give me an unsmoothed expert enthused to share over a slick celebrity paid to learn any day of the week.

The good news is that there are green shoots of fresh geek-dom on our screens. With a doffed cap to the storytelling talents of scientist Dr Hannah Fry, the numero uno of nerds is Guy Martin.

First spotted by TV producers on his bike in a 2009 TT race, the Grimsby-born presenter brings his love for all things mechanical to TV, from building a boat to breaking the world record for the fastest toboggan. Refreshingly averse to celebrity over substance (he said no to hosting Top Gear), Martin must navigate authenticity with keeping producers happy.

His latest series explores "proper jobs"– which I’m guessing means those requiring pre-dawn starts and dirty hands (strangely, I’ve not yet received the call), and it’s something he clearly admires. Nearly two decades after stardom beckoned, he still turns down TV work in favour of mending lorries and driving tractors.

There are plenty out there. If you don’t recognise the name Wintergatan, you’re not one of the 276 million who have tuned into YouTube to watch this Swedish band’s frontman Martin Molin play an instrument he built using 2,000 marbles. Subsequently, Molin abandoned the project, calling it unreliable for the planned world tour. Like Martin, this techie is not for turning.

On paper, Francis Bourgeois sounds dreadful: "TikTok content producer, brand ambassador, model." But at heart, he's a trainspotter, whose enthusiasm for all things locomotive has garnered millions of followers on social media.

For a Channel 4 doc, he flirts with the idea of going to space and has a reality check when he prepares to meet a real astronaut: "I have to carry my engineering expertise to this meeting. The power of social media, that can only take one so far."

Well, indeed, but in an age where we no longer learn how to mend a Land Rover, sew a dress or demolish a chimney, it is the modern mastery of such self-promotion that is key to promoting these skills and passions past, and where we’re reminded that there is no happier companionship than a shared niche.

When Guy Martin's host family of dairy farmers throw him a party, the bubbly is popped, the burgers are turned, but where’s Guy? In a corner, showing the farmer’s son what ChatGPT has to say about hydraulic engine fluids. Doing stuff. Enthralled, enthralling.
Mission to Space with Francis Bourgeois begins on Sunday 25 January at 6:50pm on Channel 4.
