Cooking is the root of all evil

If we hadn’t learned to roast meat, many of society's ills would never have happened.

The evil that chefs do lives after them. Until his death on 24 June, the Galapagos turtle known as Lonesome George was the rarest creature in the world, his forebears hunted to oblivion by hungry sailors.
 
Then there is the deadening legacy of the Rio+20 summit – an “epic failure”, as Greenpeace put it. We might not be eating rare species to the brink of extinction any longer but, as a result of our activities, climate change will drive many species to their doom. And it is clear that the chefs are to blame for this, too.
 
To see why, we have to take a closer look at the human brain. In order to harness resources that ensure our survival, human beings have learned a range of skills that makes us uniquely dangerous. We learned how to domesticate animals, tame wild land for agriculture, build cities and design and construct machines for rapid travel over vast distances.
 
It takes extraordinary cognitive abilities to pull all this off. Which makes it all the more remarkable that the human brain is not particularly unusual. An analysis published in the 25 June edition of the Proceedings of the National Academy of Sciences of the United States of America shows that a human being’s brain is just a scaled-up version of the generic primate brain.
 
The human brain has about 85 billion of the glial cells that provide a scaffold for the information-processing neuron cells – of which there are roughly 86 billion. This is the same ratio of processing cells to support cells as found in other primate brains. The common report of ten (sometimes 50) times as many neurons as support cells is false.
 
Then there is the claim that the human cerebral cortex, the outer covering of grey matter, is particularly rich in neurons. It is not: the ratio of normal, cerebellar neurons to cortical neurons is the same in human beings as in every other mammal, adjusting for how the density of neurons varies with brain size. 
 
Brain size does differ wildly across nature. But many creatures have large brains only because they have large neurons; a tenfold increase in the number of neurons in a rodent cortex results in a fiftyfold increase in brain size. Primates, on the other hand, pack small neurons: ten times as many neurons give a brain only ten times bigger.
 
Basically, our advanced cognitive abilities arose because we have packed the largest number of neurons into one network. Our brain size seems to have crossed a threshold, a tipping point that switches on the kind of innovative thinking that launches technological development on a scale that can change a planet.
 

Meat is murder

 
The thing is that those extra neurons use up a lot of calories, calories to which the great apes can’t get access. Neither could the earliest human beings. But somewhere in early human evolution, we managed to find the extra few hundred kilocalories a day necessary for our brain expansion. How did we do it? By harnessing fire. Put simply, cooked food yields much more energy than raw.
 
So, it was the first chefs who created the modern human – and all the devastation its brain has unleashed. The cooking of Galapagos turtles was only the final act of the chefs; without the first of their kind, Lonesome George would not have been lonesome at all. If we hadn’t learned to cook, we would never have been able to come up with the means of global travel, prompting us to look for food in far-off places.
 
Without roasted meat, there would have been no Industrial Revolution, no devastation of swaths of Planet Earth’s animal and plant species, no catastrophic climate change. The politicians are off the hook – bring me the head of Jamie Oliver.

Jonn Elledge and the Young Hagrid Audition

I auditioned for Harry Potter and the Chamber of Secrets, for the part of “Young Hagrid”. Except I didn’t.

I’ve been dining out for years now on the fact I auditioned for Harry Potter and the Chamber of Secrets, for the part of “Young Hagrid”. It’s one of those funny stories I tell people when a bit drunk, under the no doubt entirely wrong impression that it makes me sound like I’ve lived an interesting life.

Except, when I came to write this thing, I realised that it’s not actually true. I didn’t actually audition for the part of Young Hagrid at all.

Technically, I auditioned to be Voldemort.

Let’s start from the beginning. In November 2001 I was in my last year at Cambridge, where I split my time roughly equally between pissing about on a stage, writing thundering student paper columns about the true meaning of 9/11 as only a 21-year-old can, and having panic attacks that the first two things would cause me to screw up my degree and ruin my life forever. I was, I suppose, harmless enough; but looking back on that time, I am quite glad that nobody had yet invented social media.

I was also – this is relevant – quite substantially overweight. I’m not a slim man now, but I was much heavier then, so much so that I spent much of my later adolescence convinced that my mum’s bathroom scales were broken because my weight was, quite literally, off the scale. I was a big lad.

Anyway. One day my friend Michael, with whom I’d co-written quite a bad Edinburgh fringe show eighteen months earlier, came running up to me grasping a copy of Varsity. “Have you seen this?” he panted; in my memory, at least, he’s so excited by what he’s found that he’s literally run to find me. “You have to do it. It’d be brilliant.”

“This” turned out to be a casting call for actors for the new Harry Potter movie. This wasn’t unusual: Cambridge produces many actors, so production companies would occasionally hold open auditions in the hope of spotting fresh talent. I don’t remember how many minor parts they were trying to cast, or anything else about what it said. I was too busy turning bright red.

Because I could see the shameful words “Young Hagrid”. And I knew that what Michael meant was not, “God, Jonn, you’re a great actor, it’s time the whole world got to bask in your light”. What he meant was, “You’re a dead ringer for Robbie Coltrane”.

I was, remember, 21 years old. This is not what any 21-year-old wants to hear. Not least since I’d always suspected that the main things that made people think I looked like Robbie Coltrane were:

  1. the aforementioned weight issue, and
  2. the long dark trench coat I insisted on wearing in all seasons, under the mistaken impression that it disguised (a).

Most people look back at pictures of their 21-year-old self and marvel at how thin and beautiful they are. I look back and and I wonder why I wasted my youth cosplaying as Cracker.

The only photo of 2001 vintage Jonn I could find on the internet is actually a photo of a photo. For some reason, I really loved that tie. Image: Fiona Gee.

I didn’t want to lean into the Coltrane thing; since childhood I’d had this weird primal terror that dressing up as something meant accepting it as part of your identity, and at fancy dress parties (this is not a joke) I could often be found hiding under tables screaming. And I didn’t want to be Hagrid, young or otherwise. So I told Michael, quite plainly, that I wasn’t going to audition.

But as the days went by, I couldn’t get the idea out of my head. This was an audition for a proper, actual movie. I’d always had this idea I must have some kind of talent*, and that Cambridge was where I would find out what it was**. What if this was my big break?*** What if I was being silly?****

So when it turned out that Michael had literally started a petition to get me to change my mind, I acceded to the inevitable. Who was I to resist the public demand for moi?

And so, I graciously alerted the people doing the casting to the fact of my existence. A few days later I got an email back inviting me to go see them in a room at Trinity College, and a few pages of script to read for them.

The first odd thing was that the script did not, in fact, mention Hagrid. The film, I would later learn, does include a flashback to Hagrid’s school days at Hogwarts. By then, though, the filmmakers had decided they didn’t need a young actor to play Young Hagrid: instead that sequence features a rugby player in a darkened corner, with a voiceover courtesy of Coltrane. The section of the script I was holding instead featured a conversation between Harry Potter and a character called Tom Riddle.

I asked my flat mate Beccy, who unlike me had actually read the books, who this person might be. She shuffled, awkwardly. “I think he might be Voldemort...?”

Further complicating things, the stage directions described Riddle as something along the lines of, “16 years old, stick thin and classically handsome, in a boyish way”. As fervently as I may have denied any resemblance between myself and Robbie Coltrane, I was nonetheless clear that I was a good match for precisely none of those adjectives.

I’m not sure what I was expecting when I went to the audition. I don’t suppose I expected Chris Columbus to be there, let alone Robbie Coltrane ready to embrace me like a long-lost son.  But I was expecting more than a cupboard containing a video camera of the sort you could buy at Dixons and a blonde woman not much older than me. She introduced herself as “Buffy” which, given that this was 2001, I am not entirely convinced was her real name.

“My friends always tell me I look like Robbie Coltrane,” I told her, pretending I was remotely enthusiastic about this fact. 

“Oh yeah,” said Buffy. “But he’s really... big isn’t he? I mean he’s a huge guy. You’re more sort of...”

Or to put it another way, if they had still been looking for a young Hagrid, they would have wanted someone tall. I’m 6’, but I’m not tall. I was just fat.

If they had been looking for a Young Hagrid. Which, as it turned out, they weren’t.

The section I read for was included in the final film, so with a bit of Googling I found the script online. It was this bit:

TOM RIDDLE Yes. I’m afraid so. But then, she’s been in so much pain, poor Ginny. She’s been writing to me for months, telling me all her pitiful worries and woes. Ginny poured her soul out to me. I grew stronger on a diet of her deepest fears, her darkest secrets. I grew powerful enough to start feeding Ginny a few secrets, to start pouring a bit of my soul back into her...

Riddle, growing less vaporous by the second, grins cruelly.

TOM RIDDLE Yes, Harry, it was Ginny Weasley who opened the Chamber of Secrets.

I mean, you can see the problem, can’t you? I don’t remember this many years on what interpretation I put on my performance. I suspect I went beyond camp and into full on panto villain, and I dread to think what I may have done to communicate the impression of “growing less vaporous”.

But what I do feel confident about is that I was absolutely bloody awful. Five minutes after arriving, I was out, and I never heard from Buffy again.

So – I didn’t become a star. You probably guessed that part already.

In all honesty, I didn’t really realise what a big deal Harry Potter was. I’d seen the first film, and thought it was all right, but I was yet to read the books; three of them hadn’t even been written yet.

I had some vague idea there was an opportunity here. But the idea I was missing a shot at being part of an institution, something that people would be rereading and re-watching and analysing for decades to come – something that, a couple of years later, at roughly the point when Dumbledore shows Harry the Prophecy, and a tear rolls down his cheek, would come to mean quite a lot to me, personally – none of that ever crossed my mind. I’d had an opportunity. It hadn’t worked out. Happened all the time.

I do sometimes like to think, though, about the parallel universe in which that audition was the start of a long and glittering career – and where the bloke who played Tom Riddle in this universe is scratching a living writing silly blogs about trains.

*I don’t.

**I didn’t.

***I wasn’t.

****I was.
