Spider-Man: Brand New Day arrived in theaters on July 31, 2026, directed by Destin Daniel Cretton and starring Tom Holland as Peter Parker. It was warmly received and went on to become a box-office hit worth more than $2 billion worldwide.
Weeks later, the film became part of a bigger conversation about artificial intelligence in Hollywood. The trigger was not the movie itself, but a book about it.
What happened
The 208-page art book, Spider-Man: Brand New Day: The Art of the Movie, was released on August 18. Within days, fans noticed that one piece of concept art, a New York street scene titled "Big City, Little Spider," showed oddities often linked to generative AI: warped taxis, distorted buildings, strange windows, and a damaged fire escape.
The criticism spread quickly on social media. Some fans argued that a collector's book celebrating the work of human artists should not include AI imagery, especially at a premium price.

What is still disputed
Much of the story rests on allegations, so it helps to separate what is established from what is not.
- One image, not many: Coverage broadly agrees that only this one piece raised serious flags among the hundreds of images in the book. Some fans claim there are more, but other observers disagree.
- No comment from the studio: Marvel Studios has not publicly confirmed or denied AI involvement in the artwork.
- Photoshop or AI? Several artists said the artifacts could come from Photoshop's fill tool, which can resemble AI output. Others pointed out that Photoshop's fill tool is itself generative.
- Conflicting insider claims: A person who said they worked on the book's layout stated they believed no AI art was in it. They also said freelancers had been reported to use AI for backgrounds in their own assets, and that flagged material was either not supplied or was removed. These are anonymous online claims and have not been verified.
The film itself
No credible allegations have been made that generative AI was used in the finished movie. The controversy concerns concept art in a tie-in book. It is worth remembering that concept art is exploratory by nature, but today it routinely ends up in portfolios, behind-the-scenes videos, and printed books, which makes it public.
Why it hit a nerve
The timing made things worse. The discovery came after Disney cut a large number of jobs at Marvel Studios, with the concept art department reportedly hit hard. Marvel also has history here: its 2023 series Secret Invasion drew criticism for an AI-assisted opening sequence.
The debate is also bigger than Marvel. Other recent films, including Supergirl and Masters of the Universe, have faced similar accusations over concept art. Meanwhile, directors Joe and Anthony Russo have called AI a potentially valuable tool as long as artists stay in control.
The bigger question
Whether this turns out to be one freelancer's shortcut, a Photoshop misunderstanding, or something more, the lesson is the same. Audiences are paying close attention, and they want transparency about where AI is used and where human craft still leads.
Studios that say nothing risk letting online speculation fill the gap. For a franchise as beloved as Spider-Man, that conversation is likely to continue long after the box-office numbers fade.
