Christopher Nolan’s explosion

In May, Total Film reported that the production team of Tenet, led by director Christopher Nolan, found that using a second-hand Boeing 747 was better than recreating a scene involving an exploding plane with miniatures and CGI. I’m not clear how exactly it was better; Total Film only wrote:

“I planned to do it using miniatures and set-piece builds and a combination of visual effects and all the rest,” Nolan tells TF. However, while scouting for locations in Victorville, California, the team discovered a massive array of old planes. “We started to run the numbers… It became apparent that it would actually be more efficient to buy a real plane of the real size, and perform this sequence for real in camera, rather than build miniatures or go the CG route.”

I’m assuming that by ‘numbers’ Nolan means the finances. That is, buying and crashing a life-size airplane was more financially efficient than recreating the scene with other means. This is quite the disappointing prospect, as must be obvious, because this calculation limits itself to a narrow set of concerns, or just one as in this case – more bang for the buck – and consigns everything else to being negative externalities. Foremost on my mind is carbon emissions from transporting the vehicle, the explosion and the debris. If these costs were factored in, for example in terms of however much the carbon credits would be worth in the region where Nolan et al filmed the explosion, would the numbers have still been just as efficient? (I’m assuming, reasonably I think, that Nolan et al aren’t using carbon-capture technologies.)

However, CGI itself may not be so calorifically virtuous. I’m too lazy in this moment to cast about on the internet for estimates of how much of the American film industry’s emissions CGI accounts for. But I did find this tidbit from 2018 on Columbia University’s Earth Institute blog:

For example, movies with a budget of $50 million dollars—including such flicks as Zoolander 2, Robin Hood: Prince of Thieves, and Ted—typically produce the equivalent of around 4,000 metric tons of CO2. That’s roughly the weight of a giant sequoia tree.

A ‘green production guide’ linked there leads to a page offering an emissions calculator that doesn’t seem to account for CGI specifically; only broadly “electricity, natural gas & fuel oil, vehicle & equipment fuel use, commercial flights, charter flights, hotels & housing”. In any case, I had a close call with bitcoin-mining many years ago that alerted me to how energy-intensive seemingly straightforward computational processes could get, followed by a reminder when I worked at The Hindu – where the two computers used to render videos were located in a small room fit with its own AC, fixed at 18º C, and when they were rendering videos without any special effects, the CPUs’ fans would scream.

Today, digital artists create most CGI and special effects using graphics processing units (GPUs) – a notable exception was the black hole in Nolan’s 2014 film Interstellar, created using CPUs – and Nvidia and AMD are two of the more ‘leading’ brands from what I know (I don’t know much). One set of tests whose results a site called ‘Tom’s Hardware’ reported in May this year found an Nvidia GeForce RTX 2080 Ti FE GPU is among the bottom 10% of performers in terms of wattage for a given task – in this case 268.7 W to render fur – among the 42 options the author tested. An AMD Radeon RX 5700 XT GPU consumed nearly 80% as much for the same task, falling in the seventh decile. A bunch of users on this forum say a film like Transformers will need Nvidia Quadro and AMD Firepro GPUs; the former consumed 143 W in one fur-rendering test. (Comparability may be affected by differences in the hardware setup.) Then there’s the cooling cost.

Again, I don’t know if Nolan considered any of these issues – but I doubt that he did – when he ‘ran the numbers’ to determine what would be better: blowing up a real plane or a make-believe one. Intuition does suggest the former would be a lot more exergonic (although here, again, we’re forced to reckon with the environmental and social cost of obtaining specific metals, typically from middle-income nations, required to manufacture advanced electronics).

Cinema is a very important part of 21st century popular culture and popular culture is a very important part of how we as social, political people (as opposed to biological humans) locate ourselves in the world we’ve constructed – including being good citizens, conscientious protestors, sensitive neighbours. So constraining cinema’s remit or even imposing limits on filmmakers for the climate’s sake are ridiculous courses of action. This said, when there are options (and so many films have taught us there are always options), we have a responsibility to pick the more beneficial one while assuming the fewest externalities.

The last bit is important: the planet is a single unit and all of its objects occupants are wildly interconnected. So ‘negative externalities’ as such are more often than not trade practices crafted to simplify administrative and/or bureaucratic demands. In the broader ‘One Health’ sense, they vanish.

Gods of nothing

The chances that I’ll ever understand Hollywood filmmakers’ appetite for films based on ancient mythology is low, and even lower that I’ll find a way to explain the shittiness of what their admiration begets. I just watched Gods of Egypt, which released in 2016, on Netflix. From the first scene, it felt like one of those movies that a bunch of actors participate in (I can’t say if they perform) to have some screen time and, of course, some pay. It’s a jolly conspiracy, a well-planned party with oodles of CGI to make it pleasing on the eyes and the faint hope that you, the viewer, will be distracted from all the vacuity on display.

I’m a sucker for bad cinema because I’ve learnt so much about what makes good cinema good by noticing what it is that gets in the way. However, with Gods of Egypt, I’m not sure where to begin. It’s an abject production that is entirely predictable, entirely devoid of drama or suspense, entirely devoid of a plot worth taking seriously. Not all Egyptian, Green, Roman, Norwegian, Celtic and other legends can be described by the “gods battle, mortal is clever, revenge is sweet” paradigm, so it’s baffling that Hollywood reuses it as much as it does. Why? What does it want to put on display?

It surely is neither historical fidelity nor entertainment, and audiences aren’t wowed by much these days unless you pull off an Avatar. There is a glut of Americanisms, including (but not limited to) the habit of wining one’s sorrows away, a certain notion of beauty defined by distinct clothing choices, the sole major black character being killed off midway, sprinklings of American modes of appreciation (such as in the use of embraces, claps, certain words, etc.), and so forth. And in all the respect that they have shown for the shades of Egyptian lore, which is none, what they have chosen to retain is the most (white) American Americanism of all: a self-apotheosising saviour complex, delivered by Geoffrey Rush as the Sun god Ra himself.

 

There seems to be no awareness among scriptwriters angling at mythologies of the profound, moving nuances at play in many of these tales – of, for example, the kind that Bryan Fuller and Michael Green are pulling off for TV based on Neil Gaiman’s book.

There is no ingenuity. In a scene from the film, a series of traps laid before a prized artifact are “meant to lure Horus’s allies to their deaths” – but they are breachable. In another – many others, in fact – a series of barriers erected by the best builders in the world (presumably) are surmounted by a lot of jumping. In yet another, an important character who was strong as well as wily at the beginning relies on just strength towards the end because, as he became supposedly smarter by appropriating the brain of the god of wisdom, he gave himself a breakable suit of armour. Clearly, someone’s holding a really big idiot ball here. It’s even flashing blue-red lights and playing ‘Teenage wasteland’.

Finaly, Gods of Egypt makes no attempt even to deliver the base promise that some bad films make – that there will be a trefoil knot of a twist, or a moment of epiphany, or a well-executed scene or two – after which you might just be persuaded to consign your experience to the realm of lomography or art brut. I even liked Clash of the Titans (2010) even though it displayed none of these things; it just took itself so seriously.

But no, this is the sort of film that happens when Donald Trump thinks he’s Jean-Michel Basquiat. It is a mistake, an unabashed waste of time that all but drools its caucasian privilege over your face. Seriously, the only black people in the film – apart from the one major guy that dies – are either beating drums or are being saved. Which makes it all the more maddening. Remember Roger Christian’s Battlefield Earth (2000)? It was so bad – but it is still remembered because at the heart of its badness was an honest, if misguided, attempt by its makers to experiment, to exercise their agency as artists. A common complaint about the film is that Christian overused Dutch angles. I would have wept in relief if the Gods of Egypt had done anything like that. Anything at all.
