Quick test. Think of the effects shot that's lived in your head the longest. For most people I ask, it's not from the last five years. It's the shark in Jaws. It's the dinosaurs in Jurassic Park. It's a truck flipping, a building actually blowing up. There's a pattern there, and it's not just nostalgia: those things were physically in front of a camera, lit by real light, obeying real physics, and some part of your brain knows the difference even if you'd never say it out loud.
The T. Rex Test
Jurassic Park (1993) is the perfect example because it used everything. Stan Winston's crew built full-size robotic dinosaurs; ILM created the digital shots that changed the industry forever. Both are in the same film, sometimes in the same scene, so you can compare directly. And here's the thing — the moment everyone remembers, thirty-odd years later, is the T. rex attack: a giant animatronic head smashing through a car roof, in the rain, while two kids scream inside. You believe it because in a very real sense it's happening. The actors aren't imagining a monster. There's twelve feet of wet, moving machinery inches from their faces, and their fear has somewhere real to point at.
Practical work also ages at a completely different speed. Plenty of all-digital films from the early 2000s already look like video games, while the miniatures in 2001: A Space Odyssey (1968) and the original Star Wars still hold up after half a century. Light is complicated and reality does it for free. A real explosion throws real debris past real faces, and the stunt team does a real, unscripted flinch — you can't render a flinch like that. Well. You can try. We'll all be able to tell.
Directors Who'd Rather Crash a Real Plane
Christopher Nolan is the patron saint of this approach, and slightly unhinged about it, which I respect. For Inception (2010) his team built a hotel corridor that actually rotated, so Joseph Gordon-Levitt could fight through shifting gravity for real. For Tenet (2020) they bought an actual Boeing 747 and crashed it into a hangar — apparently because it worked out cheaper than faking it, which tells you something about the price of good CGI. For Dunkirk (2017), real Spitfires, real Channel. The man is not interested in pretending, and his films have a weight that audiences feel in their stomachs.
George Miller went further. Mad Max: Fury Road (2015) built around 150 real vehicles and then genuinely destroyed them across the Namibian desert, with stunt performers swinging on poles bolted to moving trucks. Yes, the film used CGI — to remove safety rigs and paint the sky. The chaos itself happened. Even Marvel, the most digital factory in Hollywood, shoots its best stuff practically when it can: real suits for close-ups, real sets, actors sharing actual space. There's a reason those scenes land better than the all-green ones.
Horror Figured This Out First
Horror fans have been saying all this for decades, and horror is where the argument becomes a rout. Rob Bottin was barely into his twenties when he built the creatures for John Carpenter's The Thing (1982) — a chest that opens into teeth, a head that rips itself free and scuttles off on spider legs. It's still the benchmark for body horror, forty years later, and digital remakes don't come close, because real materials do disgusting, unpredictable things that a tidy render rarely dares to.
Or take Rick Baker's werewolf transformation in An American Werewolf in London (1981): prosthetics, air bladders and mechanical rigs, done in bright light, nowhere to hide. It won the first Oscar ever given for makeup, and no digital werewolf since has matched it — not one. Horror people understand something instinctive: a real object in the room, in the same light as the actor, reads as a threat. Pixels read as a picture of one.
In Fairness to the Computers
- You can't build a ten-thousand-strong army, a working alien ocean, or most impossible creatures out of foam and wire. Some shots simply need computers.
- Digital tools let directors design camera moves no physical rig could ever pull off.
- CGI genuinely keeps stunt performers safer on the stuff that used to hospitalise people.
- And when it's used with care — Avatar: The Way of Water (2022), Dune — it can be flat-out beautiful. I'm not a purist. I'm just picky.
The Real Answer Is Both
The lesson of the last forty years isn't old good, new bad. It's that the two work best together: build everything you possibly can, film it for real, and let the computers quietly handle the impossible bits at the edges. When directors reach for the render farm just because it's easier, audiences can smell it. When they build the monster, flip the truck and fly the plane, the film gets a pulse.
There's a money argument too, and it's a funny one. A great creature or miniature can be shot from any angle, reused, sold, and stuck in a museum — people still queue to see the models from Alien. Digital files, meanwhile, rot as software changes; studios have lost whole films' worth of effects work to dead formats. The industry seems to have noticed. Creature shops that were dying in the 2000s are booked out again, and productions now budget for hand-built monsters alongside render farms. Which means the next great effects moment of your life is probably being painted by hand in a workshop right now. Good. Let it.
