The Venice Film Festival screened a documentary where every appearance by Diesel founder Renzo Rosso was AI-generated. For brands, creators, and publishers, the trust test is no longer just whether synthetic media looks real. It is whether audiences are told what they are seeing.
Venice has now screened a documentary about a living business founder where the subject was not filmed for the documentary at all.
Be Brave, directed by Francesco Carrozzini, premiered on September 10, 2026, at the 83rd Venice International Film Festival. The film tells the story of Renzo Rosso, the founder of Diesel and chairman of OTB Group, the fashion holding company behind Diesel, Jil Sander, Maison Margiela, Marni, Viktor&Rolf, and other brands.
The unusual part is not that the film used AI. It is how central AI was to the film’s treatment of its subject.
Reuters reported that Be Brave combines real interviews, archive material, and AI-generated video. But Carrozzini said Rosso himself was not filmed for the documentary. “Not a single frame of Renzo was filmed,” he told reporters.
That distinction matters. This is not a case where a filmmaker used AI for a few transitional shots, background fixes, or animated reconstructions. Every on-screen version of Rosso, from childhood to adulthood, was built as synthetic footage.
Venice put synthetic documentary footage on the main stage
The official Venice listing placed Be Brave in the Venice Open, Out of Competition section. It lists Carrozzini as director, with production by Our Films, a Mediawan company, and producers Lorenzo Mieli, Mario Gianani, and Gabriele Immirzi.
La Biennale describes the project as a documentary that uses AI as part of its storytelling method and as a way to start a discussion about creativity and technological progress. ANSA reported that Carrozzini described AI as being used across much of the film, including material tied to archives and interviews.
The film still includes actual filmed conversations with figures such as Anna Wintour and John Galliano, according to Reuters. That is why the claim needs precision: the documentary is not pure synthetic video from start to finish. The radical move is that the subject of the documentary, Rosso, appears through AI-generated reconstruction rather than newly filmed footage.
That choice changes the viewer’s job. In a traditional documentary, the audience can usually separate archive footage, talking-head interviews, and staged re-enactments. In Be Brave, the reconstruction is designed to feel continuous with documentary memory. It asks viewers to accept a life story through images that look like evidence, even when they were generated after the fact.
Rosso gave the experiment its consent
The film has one advantage many synthetic-media projects do not: the subject is alive, public, and openly supportive.
Rosso did not object to seeing himself recreated. Reuters quoted his reaction as: “I thought, wow. This is me.” He also framed the project as consistent with his business history, saying he likes doing things before other people do.
That consent changes the ethics of the project. The film is not using a dead person’s voice without permission or fabricating a public figure’s likeness in secret. Rosso participated in a project about himself and embraced the experiment.
But consent does not remove the audience problem. Viewers still need enough context to understand which images were captured by a camera and which were built by software. A subject can approve synthetic reconstruction, and the audience can still be misled if the reconstruction is not presented clearly.
That is where documentary AI becomes different from AI in a fashion campaign, a mood board, or a product mockup. Documentaries carry a truth expectation. They are not only trying to create an impression. They are asking viewers to believe they are seeing something with a traceable relationship to real events.
The documentary trust test is consent, purpose, and disclosure
AI in documentary is not automatically unethical. The question is what the technology is doing, who benefits from it, and whether the audience is told enough to judge it.
Two earlier documentary examples show the difference.
In Roadrunner, the 2021 Anthony Bourdain documentary, director Morgan Neville used AI to recreate Bourdain’s voice for lines that did not exist as audio recordings. CBS News reported that the technique was not widely understood by viewers until after release, and the disclosure created backlash.
In Welcome to Chechnya, director David France used AI face replacement to protect LGBTQ+ subjects facing persecution. MIT’s Open Documentary Lab described the technique as a way to hide identities while preserving emotional connection with the people on screen. The protection purpose was clear, and the use of synthetic faces was disclosed.
That gives filmmakers, brands, and publishers a practical test:
- Did the person agree to the synthetic use?
- Does the AI serve protection, clarity, access, or only spectacle?
- Can viewers tell what was generated before it affects their trust?
Be Brave performs well on the first question because Rosso consented. It is more complex on the second and third. The AI solves a storytelling problem by showing parts of Rosso’s life where intimate footage did not exist. But the more convincing the footage becomes, the more disclosure has to carry.
Europe has already moved from debate to rules
This conversation is not only cultural anymore. The EU AI Act’s transparency rules began applying on August 2, 2026, a little over a month before Be Brave premiered.
The European Commission says certain AI-generated or AI-manipulated content must be marked so it can be detected as synthetic. For deepfakes, deployers must disclose that the content was artificially generated or manipulated. The Commission’s guidance also says creative, satirical, artistic, or fictional works can disclose AI use in a way that does not spoil the experience, but disclosure still has to be understandable to the audience.
That is the new operating environment for anyone publishing synthetic people, voices, events, or scenes. The question is not whether AI can make convincing media. It can. The question is whether the disclosure arrives early enough and clearly enough for the audience to keep trusting the publisher.
Film festivals are moving in the same direction. Sundance added optional generative AI questions to its nonfiction application in 2025, asking filmmakers to explain how they used the technology and how they plan to disclose it. The Archival Producers Alliance has also urged documentary teams to be careful with synthetic primary-source material, especially when it could be mistaken for authentic archive footage.
None of that bans AI. It puts pressure on creators to document their choices.
Brands should treat synthetic media as a trust decision
The business lesson from Be Brave is not limited to film.
If your company uses AI-generated founders, customer scenarios, product demos, testimonial-style visuals, stock-style people, or executive voice clones, your audience is making the same judgment documentary viewers make: did this happen, or was this built?
That does not mean every AI-assisted asset needs a courtroom-style explanation. It does mean the audience should not have to play detective. If synthetic media affects what people believe about a person, product, result, place, or customer experience, disclosure becomes part of the asset.
Tech Help Canada’s guide to AI ethics in digital marketing covers the broader governance side of that decision. The same principle applies here: if AI changes what the audience thinks they are seeing, the use needs to be intentional, documented, and visible enough to protect trust.
The risk is not only legal. It is relational. Once people feel tricked, the correction rarely restores the original level of confidence. A label before the reveal feels like transparency. A label after criticism feels like damage control.
That is why Be Brave is useful beyond cinema. It shows how quickly synthetic media can move from experiment to audience expectation. Today, a Venice documentary can rebuild a founder’s childhood with AI. Tomorrow, a brand can do the same with a customer story, a product demonstration, or a founder narrative.
The organizations that handle this well will not be the ones that avoid AI altogether. They will be the ones that make the synthetic parts legible before trust gets spent.
If your content strategy depends on credibility, Tech Help Canada’s guide to transparency in business is the better long-term frame: tell people what they are looking at before they have to ask.
Venice did not settle the documentary AI debate. It made the next standard harder to ignore. When synthetic media can pass as captured reality, disclosure is not a footnote. It is part of the work.
Frequently asked questions
What is Be Brave?
Be Brave is a documentary about Diesel founder and OTB Group chairman Renzo Rosso. It premiered on September 10, 2026, at the 83rd Venice International Film Festival in the Venice Open, Out of Competition section.
Was Renzo Rosso actually filmed for Be Brave?
Director Francesco Carrozzini said Rosso was not filmed for the documentary. Reuters reported that the film combines real interviews, archive material, and AI-generated video, but every on-screen appearance by Rosso was generated rather than newly captured on camera.
Who directed Be Brave?
Be Brave was directed by Francesco Carrozzini. The official Venice listing names Our Films, a Mediawan company, as the production company, with Lorenzo Mieli, Mario Gianani, and Gabriele Immirzi as producers.
Why is Be Brave unusual for a documentary?
The film uses AI reconstruction for its living subject instead of filming him directly. That raises a disclosure question: documentary viewers need to know when footage was captured by a camera and when it was created later by software.
What does Be Brave mean for brands using AI content?
The lesson for brands is that synthetic media should be disclosed before it affects audience trust. If AI-generated people, voices, customer stories, or product visuals could change what viewers believe, the AI use should be clear enough that people do not feel misled.
