Which movies have had dialogue written by AI?
No major studio feature film has ever had its dialogue written by AI and credited that way. The real examples are short films — most famously the 9-minute 'Sunspring' (2016), scripted entirely by a neural network calling itself Benjamin. Under the WGA's 2023 contract, AI-generated material cannot be a credited writer on covered films.
Why — the first-principles explanation
The gap between what people imagine and what has actually shipped comes down to credit rules and liability, not technology. A language model could draft feature-length dialogue tomorrow. The reason none is credited in a studio release is that the 2023 Writers Guild of America agreement — the deal that ended a 148-day strike — established that AI-generated material is not 'literary material' and cannot be used to undermine a human writer's credit or compensation. A studio can hand a writer AI output as raw material, but the credited writer stays human, and the writer can refuse to work with it. So even where models are used, they are used invisibly, as an unattributed drafting tool. There is no reliable way to count that from the outside.
The second reason is that AI dialogue is genuinely bad at the thing dialogue must do. A model predicts the next likely token. Good dialogue is the opposite of likely — it's a character saying the specific, surprising, slightly wrong thing that only that person would say, in service of a scene's turn. Models regress to the mean of everything they've read, which produces lines that are grammatical, plausible, and inert. This is exactly what happened in Sunspring (2016), directed by Oscar Sharp and starring Thomas Middleditch: an LSTM network trained on decades of sci-fi screenplays produced a script that is coherent word by word and total nonsense scene by scene. It's watchable as comedy, not drama. Its 2017 follow-up 'It's No Game,' featuring David Hasselhoff, worked the same way.
Where AI has genuinely entered released films is a different job: voice, not writing. 'The Brutalist' (2024) drew controversy for using Respeecher to refine its actors' Hungarian pronunciation — the words were written and performed by humans, and a model adjusted the accent. That distinction matters and is constantly blurred in headlines. Editing how a line sounds is not writing the line.
So the honest answer to 'which movies' is: shorts and experiments, plus an unknown amount of uncredited drafting assistance that nobody discloses. If you see a viral claim that a specific blockbuster's script was AI-written, the burden of proof is on that claim, and it has not yet been met for any of them.
An example that makes it click
Think of a model as someone who has read every screenplay ever written but has never been in a room with another person. Ask them to write a breakup scene and they'll produce something perfectly average: "I think we need to talk." "I know." "It's not you." Every line is correct. Nothing is true.
Now think about the breakup scenes you actually remember. Someone says something about a parking ticket. Someone laughs at the wrong moment. The line lands because it's the one thing you wouldn't have guessed — and "wouldn't have guessed" is precisely what a next-word predictor is built to avoid. That's why 'Sunspring' plays like a very good joke and not like a movie: the machine nailed the grammar of screenwriting and missed the point entirely.
Key facts
- 'Sunspring' (2016), a 9-minute science fiction short directed by Oscar Sharp and starring Thomas Middleditch, was scripted entirely by an LSTM neural network that named itself Benjamin — the best-documented case of fully AI-written film dialogue.
- The same team's follow-up, 'It's No Game' (2017), featuring David Hasselhoff, also used Benjamin-generated dialogue.
- The Writers Guild of America's 2023 Minimum Basic Agreement, which ended a 148-day strike, established that AI-generated material is not 'literary material' and cannot receive writing credit on covered productions.
- No wide-release studio feature film has been credited as having AI-written dialogue as of 2026-07.
- 'The Brutalist' (2024) used Respeecher voice AI to refine actors' Hungarian pronunciation — this modified how human-written lines sounded, not who wrote them.
- 'The Electric State' (2025), often named in AI-script rumors, credits its screenplay to human writers Christopher Markus and Stephen McFeely.
▶ The 60-second explainer (script)
Which movies have had dialogue written by AI? The honest answer: no major studio feature, ever. The real examples are short films. The famous one is Sunspring, a nine-minute sci-fi short from 2016, directed by Oscar Sharp and starring Thomas Middleditch. Its entire script came from a neural network that named itself Benjamin, trained on decades of sci-fi screenplays. A 2017 follow-up called It's No Game did the same thing with David Hasselhoff. Watch Sunspring and you'll immediately understand why this hasn't scaled. The dialogue is grammatical line by line and complete nonsense scene by scene. That's not a bug you can train away — it's the mechanism. A model predicts the next likely word. But good dialogue is the opposite of likely. It's a character saying the specific, surprising, slightly wrong thing only that person would say. Models regress toward the average of everything they've read, which gives you lines that are plausible and totally inert. There's also a rules reason. The Writers Guild's 2023 contract, the one that ended a 148-day strike, established that AI-generated material is not literary material and can't take writing credit. A studio can hand a writer AI output as raw material, but the credited writer stays human. So if models are used at all, they're used invisibly, and nobody discloses it. One thing that gets constantly confused: The Brutalist used voice AI to refine its actors' Hungarian pronunciation. Humans wrote those lines and performed them. A model adjusted the accent. Editing how a line sounds is not writing the line. If you see a viral claim that some blockbuster's script was AI-written, the burden of proof is on that claim — and so far, for every one of them, it hasn't been met.
What authoritative sources say
People also ask
Was any Marvel or Netflix blockbuster's script written by AI?
No credible reporting supports that for any wide-release feature as of 2026-07. Films that 'feel' AI-written — a common complaint about 2025's The Electric State — have human-credited screenwriters.
What is Sunspring?
A 9-minute 2016 sci-fi short directed by Oscar Sharp, starring Thomas Middleditch, with a script generated entirely by an LSTM neural network that named itself Benjamin. It's the clearest real example of AI-written film dialogue.
Can AI legally be credited as a screenwriter?
Not on WGA-covered productions. The Guild's 2023 agreement holds that AI-generated material isn't 'literary material' and can't receive writing credit or displace a human writer's compensation.
Do screenwriters secretly use ChatGPT?
Some certainly use models for brainstorming or drafts, and there's no disclosure requirement for that. Because the credited writer must be human, any such use is invisible from the outside and can't be counted.
Isn't The Brutalist an example of AI in a movie?
Yes, but not of AI writing. It used Respeecher to refine the actors' Hungarian pronunciation. The lines were written and performed by people; a model adjusted the accent.
