Guillermo del Toro: Why AI Can't Replace Creative Alchemy

Guillermo del Toro is not having it. Short answer: machines can simulate surfaces, but they can't live inside a story. He said as much during a Reddit r/movies Q&A on September 9, when a fan asked him to clarify remarks from his 2024 talk at the British Film Institute.

Del Toro's point punched past the usual tech-versus-art headlines. "The value of art isn't how little money or effort it takes," he told the audience. "It's how much risk you take to be present with it." Three short clauses. Heavy with meaning.

He went on to sketch what that risk looks like in practice. AI, he argued, is efficient at getting you halfway there — a fast track to the middle of the room. But the last leg, the eccentric, stubborn mile, is where judgment, accident and time reshape an idea into something rare. "Three quarters of the process gives you room to think of an idea that people wouldn't think of without that process," he said. "AI can get you quickly to the midpoint, but there's reasoning in the process that lifts you into the top ten percent."

Stories like how the Pale Man came to life in Pan's Labyrinth illustrate his point. Del Toro described starting with the notion of an old man. Then something odd happened: memories of a stingray image and a Phantasm poster—two unlikely sources encountered weeks apart—collided in his head. He scrapped the face idea. He moved the eyes to the hands. Little, strange choices accumulated. They didn't arrive as a tidy formula. They were accidents, dwellings and slow editings over months. That, he said, is alchemy.

Creativity is alchemy, not an algorithm.

Put another way: art often benefits from the messy, nonlinear parts of creation—those private experiments, the detours and dead ends that no dataset can replicate. Machines can copy patterns. They can combine and optimize. But can they take the emotional risk of living with an image for a month, returning to it, changing it until it hurts? Del Toro thinks not.

He didn't dismiss AI outright. He acknowledged its power to generate ideas and speed up certain tasks. His concern is about what gets lost when speed replaces slowness, when quick synthesis replaces prolonged curiosity. If art is measured by the gamble of presence, then automation is a very different currency.

So where does that leave filmmakers and artists wrestling with new tools? Use them, learn from them, but don't outsource the weird private work that turns a concept into a creature that haunts you. Do you want a machine's halfway answer, or the slow burn of discovery?
