AI Is Already on Screen. Here’s Where Film Drew the Line

A brand deciding where AI belongs in its video can look at what feature films have already done, because cinema ran the experiment in public. Between late 2024 and the summer of 2026, AI reached the screen in an Oscar-winning performance, in a film where two stars age across a lifetime, and in an animated feature made with AI tools. It also produced one loud rejection and two new rulebooks.

The pattern is consistent. AI that adjusts a human performance, with the performer’s consent, has mostly been absorbed. AI that stands in for the human is where the industry pushed back. And AI use that comes out late turns a small edit into a story. Each of those lessons transfers to brand video with very little translation.

A few Hungarian vowels in an Oscar-winning role

In January 2025, The Brutalist’s editor, Dávid Jancsó, told the trade site RedShark News that an AI voice tool had been used on the film’s Hungarian dialogue, spoken by Adrien Brody and Felicity Jones. TheWrap relayed the interview. “It’s mainly just replacing letters here and there,” Jancsó said. The film was a leading Oscar contender, and the backlash was immediate.

Director Brady Corbet answered within days. The tool was used “in Hungarian language dialogue editing only,” he said, to refine certain vowels and letters, and no English was changed. Both actors had worked for months with a dialect coach. NPR reported that Brody performed his Hungarian lines himself, and that they were then refined by the editor and a few hired voiceover artists.

On March 2, 2025, Brody won the Oscar for best actor. A machine touching up a performance that already existed did not cost him the award. What hurt the film was the timing: the detail surfaced in an interview, deep into an awards campaign, and looked like something kept quiet.

This is the most common use of AI in brand video and the least visible one: fixing a mispronounced product name, cleaning a line recorded next to a noisy production line, tightening a spokesperson’s vowels in a second language. Voice tools of this kind resynthesize a few sounds in the speaker’s voice and leave the rest of the take as it was performed. The edit is accepted when the speaker agreed to it and when the brand says so before anyone else does.

Here: every age played by the same two actors

Robert Zemeckis’s Here, released on November 1, 2024, follows a couple across decades. Tom Hanks plays his character from an idealistic teenager to a frail old man, and Robin Wright ages alongside him. According to AFP, Zemeckis worked with an AI visual effects studio whose system de-aged and aged the actors in real time, on monitors on set, alongside traditional makeup. Hanks called it “amazing,” while acknowledging that the technology was causing huge concern in Hollywood.

The faces changed and the performances did not. A system like this transforms a take captured on set; it does not invent the gesture or the line reading. Seeing the result live also let the director judge each transformed face during the take, instead of discovering it months later in post-production.

Generated video gives a brand similar options. Video-to-video work can restyle or age a filmed take while keeping its timing, and a filmed product can be composited into a generated set. The habit worth copying from Here is the preview. Checking every transformed shot against the original take catches a drifting jawline, a warped logo or a shifting label before it multiplies across a campaign.

Where the line held: no performer underneath

In September 2025, an AI-generated “actress” named Tilly Norwood was presented as looking for agency representation. SAG-AFTRA answered on September 30 that “creativity is, and should remain, human-centered,” and that it opposes replacing human performers with synthetics. The union argued that such characters are built from performers’ work used without permission or compensation, and reminded producers that its contracts require notice and bargaining whenever a synthetic performer is going to be used.

The difference with The Brutalist and Here is simple. Brody and Hanks performed every scene; Norwood has no one underneath.

Studios have hit the same wall from the rights side. Lionsgate announced a partnership with an AI video company in 2024 to train a model on its film library. A year later, TheWrap reported that the plan had run into limits. “The Lionsgate catalog is too small to create a model,” one insider said, and an attorney warned that the right to make an actor appear to say something new gets complicated fast.

A brand’s footage library is far smaller, and the rights question is the same. Owning last year’s campaign does not mean the people in it agreed to have a model generate new lines, gestures or ads from their likeness. A fully synthetic brand face avoids that contract problem only by taking on the one SAG-AFTRA named: nobody is performing.

The rules written in 2026

Awards bodies turned that pattern into eligibility rules this year. On May 1, 2026, the Academy approved its rules for the 99th Oscars. Screenplays must be human-authored. In the acting categories, only credited roles “demonstrably performed by humans with their consent” are eligible. The Academy also reserves the right to request more information about the nature of generative AI use and human authorship.

BAFTA followed on July 22, 2026. Its awards honour human achievement in shaping the final work, “regardless of the tools used to bring this work to life,” and it may ask for details on generative AI use and the extent of human creative involvement. The guidance applies across its 2027 rulebooks, for film, games and television.

Where AI met the screen, 2024 to 2026

Accepted assists, contested replacements, and the rules that followed

AI on screen, 2024 to 2026

Date	Type	Event
NOV 2024	Accepted or kept	Here: actors de-aged and aged in real time on set
JAN 2025	Contested	The Brutalist: AI edit of Hungarian dialogue revealed
MAR 2025	Accepted or kept	Brody wins the best actor Oscar for The Brutalist
SEP 2025	Contested	SAG-AFTRA opposes a synthetic “actress”
SEP 2025	Contested	Lionsgate’s plan for a model trained on its films hits limits
MAY 2026	New rule	Oscars: roles must be played by humans who consent
MAY 2026	Accepted or kept	Critterz shows first footage to buyers at the Cannes market
JUL 2026	New rule	BAFTA: human achievement, “regardless of the tools used”

Neither body bans AI. Both ask the same two questions: did a human do the work being honoured, and can you show how the rest was made? Critterz, an animated feature its producers describe as human-led and AI-assisted, is the case to watch. In May 2026 its sales company showed first-look footage to buyers at the Cannes market, and the producers say they are targeting a release in the first quarter of 2027. The team says artists’ sketches, rather than text prompts, guide the system.

What a brand should check

Cinema’s record gives brands a working rule. AI that refines a real person or a real product, with consent, is accepted and mostly goes unnoticed. AI that replaces the person the audience believes it is watching is where trouble starts. Any AI use revealed late reads as concealment, even when it is minor.

Before approving an AI-assisted video, ask for a shot-by-shot note of what was filmed, what was generated and what was altered: the record the Academy and BAFTA now reserve the right to request. Check that every real person whose face or voice appears signed off on that specific use, and that talent contracts for any reused footage allow it. If a spokesperson or character is fully synthetic, decide before production whether and how you will say so. Then review the cut against the original takes, looking for the shot where an adjustment quietly became a replacement.
