Why Practical Effects Will Always Beat CGI: A Love Letter to Real Explosions

Why Practical Effects Will Always Beat CGI: A Love Letter to Real Explosions There’s a moment in Mad Max: Fury Road (2015) where a car flips through the air, a stuntman dangles from a swinging pole, and fire engulfs the frame - all in one unbroken shot. No green screen. No digital doubles. Just a bunch of absolute madmen in the Namibian desert risking their lives for cinema. And you can feel the difference in your bones. The Uncanny Valley of Pixels CGI has become impossibly sophisticated. Modern rendering can create photorealistic humans, cities, and creatures. Yet something fundamental remains missing - weight. When Thor’s hammer flies across the screen, your brain knows it’s weightless pixels. When the T-800 rises from flames, actually burning, your lizard brain screams that something real just happened. It’s not about technical quality. Thanos looks incredible. But compare him to the practical effects in An American Werewolf in London (1981), where Rick Baker’s transformation puppet required no suspension of disbelief because it existed in the same physical space as the actors. David’s skin really did ripple. Something really did emerge. Why Actors Perform Better With Real Things Ask any actor about working with tennis balls on sticks versus actual props, and watch their eyes light up when describing the latter. When Harrison Ford ran from that boulder in Raiders of the Lost Ark, his terror was enhanced by an actual massive fibreglass rock rolling toward him. When Jeff Goldblum encountered a dinosaur in Jurassic Park, animatronic rubber gave him something to react against. The Velociraptors in that kitchen scene remain terrifying because they existed. Puppeteers crouched inside rubber suits, manipulating creatures that cast real shadows and made real sounds. The children’s fear was genuine reaction to something genuinely there. The Texture of Reality Look closely at any practical creature - the Alien xenomorph, the Thing’s various grotesque forms, Brundlefly’s revolting flesh - and you’ll notice textures that CGI struggles to replicate. The way light catches wet rubber. The slight wobble of a suspended puppet. The imperfect symmetry of handmade creations. These “imperfections” are actually what sell reality. The human eye has evolved over millions of years to detect living things. We unconsciously register the physics of real materials, the way substances actually interact. When John Carpenter’s Thing split apart a man’s chest to form a mouth, tubes pumped actual fluids through foam latex. It was disgusting precisely because something was genuinely happening. The Economics of Spectacle Hollywood’s shift to CGI wasn’t about quality - it was about predictability. Practical effects require building real things, coordinating complex shoots, and accepting that some things might not work perfectly. CGI can be finessed endlessly in post-production, allowing directors to change their minds and studios to request revisions. But this convenience comes at a cost. When everything is possible, nothing feels special. The first Transformers film spent $150 million on digital robots that felt curiously weightless. Fury Road used every dollar to put real vehicles in real danger, and the result felt like nothing we’d seen before - because it was real. Finding the Balance The best modern films understand this. Christopher Nolan flipped an actual truck for The Dark Knight. Denis Villeneuve built real sets for Blade Runner 2049. Even the MCU, that bastion of digital excess, gets praise whenever practical elements emerge - Iron Man’s actual suit in the first film, the practical Hulkbuster in Age of Ultron. The lesson isn’t that CGI is bad - it’s an essential tool for things that can’t exist otherwise. But when you can build it, burn it, or crash it for real, the camera captures something ineffable. That stuntman really did fall. That explosion really did happen. That moment existed in our universe, and no amount of rendering power can manufacture that authenticity. So next time a filmmaker tells you they built a real set or hired actual pyrotechnicians, pay attention. In an age of unlimited digital possibility, choosing reality is a statement. It says: we believe in the magic of actually making things happen. And that hits different.
