There is a particular kind of Hollywood stubbornness that cannot be taught. Val Kilmer had it in abundance. He was the actor who did not want to play Iceman, who told Oliver Stone he would play Jim Morrison or nobody, who once asked the art department on Tombstone to fill his deathbed with ice so that he might feel the tuberculosis chill his character was meant to endure. He was the man who, when cancer stole his voice, went looking for an algorithm to give it back. Now, one year after his death on 1 April 2025 at the age of sixty-five, Kilmer has done something no amount of sheer will could accomplish in life: he has returned to the screen without ever stepping on set.
The film is As Deep as the Grave, an independent historical drama written and directed by Coerte Voorhees, and its April 2026 trailer debut at CinemaCon in Las Vegas sent a tremor through an industry already reeling from the ethical aftershocks of artificial intelligence. Kilmer appears for roughly one hour and seventeen minutes of the film’s running time as Father Fintan, a Catholic priest and Native American spiritualist suffering from tuberculosis. He never shot a single frame. Every gesture, every rasp of dialogue, was generated.
The Role That Was Always His
The story of how this performance came to exist begins in 2020, when Voorhees cast Kilmer in the part. The script, based on the true story of Southwestern archaeologists Ann and Earl Morris and their excavation at Canyon de Chelly in Arizona, was built around the actor. Father Fintan’s heritage, his spiritualism, his deteriorating health – all of it was designed to draw on Kilmer’s own Native American ancestry, his ties to the American Southwest, and, with an irony that borders on the uncanny, his real-life illness.
“He was the actor I wanted to play this role,” Voorhees told Variety in March 2026. “It was very much designed around him. I was looking at a call sheet the other day, and we had him ready to shoot. He was just going through a really, really tough time medically, and he couldn’t do it.”
Kilmer had been diagnosed with throat cancer in 2014. Two tracheotomies and rounds of chemotherapy followed. By the time Voorhees was preparing production, the actor’s voice – once capable of channelling Jim Morrison’s growl and Doc Holliday’s Southern drawl – had been reduced to a whisper. The production shut down two days after the casting director delivered the news: “He can’t do it and he’s really upset.”
What the Family Wanted
Voorhees might have recast. That is what the industry does when an actor becomes unavailable. Instead, he went to the Kilmer family. Both Mercedes Kilmer, Val’s daughter and an filmmaker in her own right who co-produced the 2021 documentary Val, and his son Jack gave their support. The estate was compensated, and family members supplied younger photographs and footage from Kilmer’s final years to train the generative AI model.
“His family kept saying how important they thought the movie was and that Val really wanted to be a part of this,” Voorhees explained. “He really thought it was an important story that he wanted his name on. It was that support that gave me the confidence to say, okay, let’s do this. Despite the fact some people might call it controversial, this is what Val wanted.”
Mercedes Kilmer has been more expansive in her reasoning. Speaking to The Today Show in April 2026, she placed the decision within a broader cultural calculus: “It’s kind of fallen into two camps. People that maybe have a more precarious position in the industry and are worried and see AI as a threat – which is absolutely valid – and younger people, younger actors and musicians. At the same time, I’ve gotten a lot of like really good responses from people – older people, people maybe more established in the industry – that see it as a way to protect that actors’ ownership of their IP. We have to contend with this technology one way or the other. And avoiding it, it’s not necessarily the way.”
She added, in a statement provided to the press: “He always looked at emerging technologies with optimism as a tool to expand the possibilities of storytelling. This spirit is something that we are all honoring within this specific film.”
The Biographical Mirror
There is a peculiar symmetry to the project that its makers have been keen to underline. Father Fintan, the historical figure Kilmer was set to portray, suffered from tuberculosis – a disease that ravages the lungs and steals the voice, much as throat cancer did to Kilmer himself. John Voorhees, the film’s producer and Coerte’s brother, framed it as a bridge between art and reality: “This historical character mirrored Val’s actual condition when he was suffering from throat cancer. And so when it comes to the voice, this is a really unique opportunity for the character to reflect the condition that the actor was actually suffering from, thus creating a kind of a bridge.”
The cast surrounding the digital Kilmer includes Tom Felton, Abigail Lawrie, Wes Studi, and Abigail Breslin. According to reports from the CinemaCon presentation, the AI version of Kilmer is not a cameo or a brief spectral appearance – it is woven into the fabric of the film, appearing consistently throughout. At the Q&A, when asked whether this constituted a genuine Val Kilmer performance, Coerte Voorhees chose his words with care: “Val Kilmer influenced this performance.”
From Iceman to Algorithm
The roots of this experiment reach back further than As Deep as the Grave. In 2021, Kilmer partnered with Sonantic, a London-based voice technology company, to digitally reconstruct his voice using archived recordings. The process required building more than forty vocal models to approximate his original tone and cadence. In a video released by Sonantic that year, Kilmer’s recreated voice said: “After getting treated, my voice as I knew it was taken away from me. But despite all that, I still feel like the exact same person – still the same creative soul. But now I can express myself again.”
He called the technology “an incredibly special gift.”
That voice model was subsequently used, in modified form, for his final screen appearance as Iceman in Top Gun: Maverick (2022), where the character communicates primarily through typed messages on a computer screen, with one brief spoken line digitally enhanced for clarity. Director Joseph Kosinski later clarified that Sonantic’s AI was not used directly in that film – Kilmer’s actual voice was digitally altered – but the partnership demonstrated the actor’s comfort with the territory.
The trajectory is unmistakable: from reluctant adopter to active collaborator, Kilmer spent his final years negotiating the boundaries between flesh and code.
The Rules of Engagement
As Deep as the Grave arrives in a landscape where the use of AI-generated likenesses remains fiercely contested. SAG-AFTRA’s 2023 television and theatrical contracts established the first comprehensive framework for digital replicas, requiring “clear and conspicuous” consent from performers, negotiated separately from standard employment contracts. For deceased performers, consent must be obtained from an authorised representative or the union itself. The guidelines stipulate that producers must provide a “reasonably specific description” of intended use, and that compensation – including pension and health contributions – must be paid.
The Voorhees team say they followed these rules to the letter. “We believe we are serving as a demonstrator for how to do it ethically and correctly, especially in the case of working with a deceased actor’s estate and family,” they stated. The IMDb listing for As Deep as the Grave credits Kilmer as a “digital performer,” specifying “AI performance as Val Kilmer.”
Whether this constitutes an ethical precedent or a cautionary tale depends on whom you ask. SAG-AFTRA has drawn a firm line against entirely synthetic performers – AI-generated actors with no real-world counterpart – while permitting the digital replication of real performers under strict conditions. Kilmer’s case, backed by family consent and estate compensation, sits within the permitted category, but it pushes at the edges of what audiences and the industry are prepared to accept.
What Remains
Val Kilmer’s career was never a straightforward ascent. He was the Juilliard-trained actor who became famous playing a character he thought was beneath him. He was the man who fought for the role of Jim Morrison and then disappeared into it so completely that Oliver Stone’s film became as much a liability as a triumph. He was the Batman who was replaced after a single outing, and the bank robber in Michael Mann’s Heat whose quieter scenes opposite Al Pacino and Robert De Niro remain among the most watched sequences in cinema education.
He was, in the words of the BBC’s obituary, “an actor’s actor” – respected by peers, frustrating to directors, and possessed of a screen presence that no amount of technical training could replicate. His 2020 memoir, I’m Your Huckleberry, named after his most quoted line from Tombstone, laid bare the contradictions: the Christian Scientist who refused conventional medicine for years, the artist who published poetry collections and submitted work to galleries, the father who appeared alongside his daughter Mercedes in the 2020 film Paydirt.
The question that As Deep as the Grave poses is not whether AI can simulate a performance – it clearly can – but whether an algorithm trained on archival footage and a family’s blessing constitutes something we ought to call acting. Voorhees’s answer, that Val Kilmer “influenced” this performance, is diplomatically precise. It sidesteps the question of authorship while acknowledging the debt.
For Kilmer, who spent his final years fighting to be heard, the irony may be the point. His voice, once lost, was rebuilt. His image, once faded, was restored. His last role, denied to him by illness, was completed by machines working from the data of a life lived on camera. He wanted to tell this story. The technology made sure he could.
As Deep as the Grave is seeking distribution and is expected later in 2026.
