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.
The dispute is narrow in scope but wide in implication. It centers on a single illustration in a printed collector’s volume, yet it touches on questions that the entertainment industry has been wrestling with for years: who is responsible for the images attached to a major film, how studios and publishers verify the work they receive, and what audiences are entitled to know about the tools behind the art they buy.
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.
The image was first flagged by an art-book collector who posts about such releases online, and it gained momentum around August 21 as posts on X and Reddit circulated close-up crops of the traffic lights, vehicles, and fire escapes. The hardcover retails for roughly $50, a detail that sharpened the frustration among buyers who expected a showcase of hand-built design work.

Photoshop, photobashing, or AI: why the line is blurry
Part of what makes this episode difficult to resolve is that several common digital-art techniques can leave behind artifacts that look similar to generative output. Concept artists routinely work with photobashing, which means assembling an image from photographs and other source material, then painting over the result. They also use clone tools to duplicate and repair areas of an image, and fill features that automatically replace unwanted content such as watermarks.
Not all of those tools are equal. Older content-aware fill functions calculate replacement pixels from the surrounding image, while newer generative fill features rely on machine-learning models to invent new detail. The distinction matters, because the second type is, by definition, a form of generative AI. Yet an image produced with the first type can still show smeared geometry, repeated patterns, or illogical architecture, particularly when a tight deadline leaves no time for cleanup.
This is why the debate has proven so hard to settle from the outside. Viewers can see the flaws, but the flaws alone do not identify their source.
The publisher’s response
As the criticism grew, a response attributed to the book’s publisher was shared in the online discussion. It described the process used for the image as relying on a cloning tool and photobashing, and it stated that the company maintains an anti-AI policy. The statement also explained that artwork for these books is supplied by studios and often originates with freelance artists working on tight schedules, and that tools such as Photoshop’s auto-fill can leave artifacts that resemble AI output when they are really the product of shortcuts like watermark removal.
The explanation added that neither Disney nor Marvel would knowingly approve AI-assisted artwork, given contractual requirements that submitted work be original, and that any decision to cut corners would rest with an individual contributor rather than reflect a studio-wide mandate. The response was relayed through social media and the Reddit thread, and Marvel Studios itself has not issued a detailed public statement.
Not everyone has accepted the account. The fan who first flagged the image later said that after consulting several artists, the piece appeared to show indicators beyond ordinary photobashing. That user also noted that the credited artist was not a current or former member of the film’s own visual development team, a detail that bears on the question of how the image entered the book.
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.
- Limited comment from the studio: Marvel Studios has not publicly confirmed or denied AI involvement in the artwork. The explanation that emerged came from the book’s publisher, as described above.
- 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.
That distinction is important for readers trying to weigh the claims. A single questionable illustration in an ancillary product does not establish how the film’s visual effects or production design were created, and the movie’s reception has been largely separate from the debate. At the same time, the episode shows how material produced early in development can resurface months later in a very different context, where it is judged by standards the original work was never meant to meet.
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 Supergirl case drew particular attention after a behind-the-scenes featurette reportedly showed director Craig Gillespie presenting what appeared to be an AI-generated mock-up to star Jason Momoa, and the video was later taken down from the studio’s official channel. Together with the layoffs, these episodes created an atmosphere in which audiences were primed to read any odd-looking image as evidence of a larger shift.
Who is accountable for an art book?
Behind-the-scenes books occupy an unusual space in the supply chain. The images come from many sources: staff artists, outside freelancers, vendors, and sometimes material that was never intended for publication. A publisher then collects those assets, designs the layout, and prints the result, often working to a schedule tied to the film’s release.
That structure makes verification difficult. A layout designer may receive hundreds of files with little documentation about how each was made, and a studio may approve the selection without reviewing every pixel. When something slips through, responsibility can seem to dissolve across several parties. Critics argue that this is precisely why clearer disclosure and stronger contractual checks are needed, while defenders point out that the system relies on trust in contributors who are contractually bound to deliver original work.
What artists and audiences are asking for
Reactions to the episode have followed a recognizable pattern. Many fans have called for clearer labeling in books and promotional materials, so that buyers know whether an image was painted, composited, or machine-generated. Working artists, who have watched their industry change quickly, have emphasized credit and consent: if a tool is used, they argue, the people affected should know about it, and the people whose work trained that tool should not be overlooked.
Others take a more cautious view. They note that a single image does not prove a trend, that the explanation offered by the publisher is plausible, and that accusations spread faster online than corrections do. For this group, the priority is careful verification before conclusions harden into reputation, particularly for an individual contributor who may have little ability to respond in public.
Both positions point toward the same practical remedy. Clear documentation of how an image was created, simple disclosure standards for printed books, and a willingness to answer questions quickly would not end the wider argument about AI in filmmaking, but they would make future disputes of this kind far easier to resolve.
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.
