Val Kilmer will star in "As Deep as the Grave" through a fully AI-generated performance, both visual and vocal, marking the first feature film where a lead actor's entire role was created with generative AI. Unlike prior posthumous digital performances that relied on body doubles with CGI face replacement, no footage of Kilmer was shot for this production. The film, his estate's approval, and the legal framework surrounding it establish a template that Hollywood will reference for years.
Background
Kilmer was cast as Father Fintan, a Catholic priest and Native American spiritualist, around 2021 by director Coerte Voorhees. The role drew on Kilmer's own Native American heritage and his deep connection to the American Southwest, where he made his home in New Mexico. But throat cancer left him too ill to ever make it to set. He died on April 1, 2025, at age 65.
Kilmer had a documented history with AI voice technology. In 2021, he partnered with Sonantic to digitally restore his speaking voice after a tracheostomy damaged his vocal cords. Working with fewer than 30 minutes of cleaned archival audio, Sonantic generated over 40 voice models to find the most expressive match. The resulting AI voice was used for his brief reprise as Iceman in "Top Gun: Maverick" (2022), where his character also had cancer and communicated mostly by typing. Sonantic was subsequently acquired by Spotify in 2022.
The production of "As Deep as the Grave," previously titled "Canyon of the Dead," has been in post-production for approximately three years. The film tells the true story of Ann Axtell Morris and Earl Morris, pioneering archaeologists who excavated Canyon de Chelly in Arizona during the 1920s, documenting evidence of Ancestral Puebloans and the history of the Navajo people. The cast includes Abigail Lawrie, Tom Felton, Abigail Breslin, Wes Studi, Tatanka Means, Jacob Fortune-Lloyd, and Finn Jones.
Deep Analysis
A New Category of Digital Performance
Hollywood has recreated deceased actors before, but every prior case involved some combination of existing footage, body doubles, or CGI face mapping. Oliver Reed died during filming "Gladiator" (2000), and The Mill completed his remaining scenes through frame-by-frame digital face replacement on a stand-in. Paul Walker's brothers Caleb and Cody stood in for his remaining "Furious 7" (2015) scenes, with Weta Digital recreating his face. Peter Cushing's role in "Rogue One" (2016) required actor Guy Henry to provide a full physical and vocal performance over 18 months, with motion capture mapping Cushing's face from a 1984 lifecast.
The Val Kilmer performance is categorically different. No stand-in. No prior footage from this production. The entire visual and vocal performance was built from younger photographs provided by his family, footage from his final years, and recordings of his post-tracheostomy voice. Director Voorhees chose the post-tracheostomy voice intentionally because Father Fintan suffers from tuberculosis, which "mirrored Val's actual condition when he was suffering from throat cancer."
The production has not disclosed which specific AI tools or companies were involved, describing only "state-of-the-art generative AI." This is a notable gap given the precedent the film sets.
The Legal Framework That Made It Possible
California AB 1836, signed by Governor Newsom on September 17, 2024, and effective January 1, 2025, prohibits the use of digital replicas of deceased performers without consent from the performer's estate. Violators face liability for the greater of $10,000 or actual damages. A companion law, AB 2602, protects living performers by barring contract provisions that enable digital replicas without informed consent and professional representation.
SAG-AFTRA's 2023 contract, ratified after the historic strike, established two categories of AI content: digital replicas of specific actors and synthetic performers that are not recognizable as any real person. For digital replicas, producers must provide 48 hours notice, obtain clear consent, and compensate the actor or estate. The contract provisions are projected to generate more than $1 billion in new compensation and benefit plan funding.
"As Deep as the Grave" checks every box. The Kilmer estate granted permission. The family actively cooperated, providing photographs and supporting the creative direction. The estate was compensated per SAG-AFTRA guidelines. Voorhees says he worked "in lockstep with the Kilmer family for over six years."
The Ethics That Will Not Stay Simple
The Kilmer case presents the cleanest possible scenario for a posthumous AI performance. The actor wanted the role. He had a documented enthusiasm for AI technology. His family approved and participated. The production followed every available legal requirement. Mercedes Kilmer stated that her father "always looked at emerging technologies with optimism as a tool to expand the possibilities of storytelling."
But the template this creates extends beyond clean cases. Not every actor leaves a clear record of their wishes regarding AI. Not every estate will make decisions aligned with what the performer would have chosen. The permissions and guardrails in this case remain private, with no public audit of what exactly was consented to and what limitations were set.
In September 2025, AI talent studio Xicoia introduced a fully AI-generated "actor" named Tilly Norwood at the Zurich Film Festival. SAG-AFTRA condemned the move, with president Sean Astin calling it "an artificially intelligent construct" and the union exploring a studio tax on digital performers. The contrast between the Kilmer case (estate-approved, legally compliant, compensated) and the Tilly Norwood case (fully synthetic, no human performer involved) illustrates the spectrum of AI performance issues the industry is navigating.
What This Means for Independent Film
Voorhees has noted that the production does not have a major studio budget. The AI approach was "cheaper and more faithful to the original vision than a total overhaul" of the film. For independent filmmakers, this opens a door that was previously accessible only to productions with massive VFX budgets.
The broader context supports this. Netflix acquired Ben Affleck's AI filmmaking startup InterPositive in March 2026 for a reported $600 million, signaling major studio investment in AI post-production tools. Steven Spielberg stated at SXSW 2026 that while he supports AI in many disciplines, he is "not for AI if it replaces a creative individual" and has never used it in his films. SAG-AFTRA recently completed a month of negotiations with major studios without reaching a new deal, with AI usage remaining a sticking point.
The tension is real. AI can enable stories that indie filmmakers "otherwise wouldn't have had the budget or time to tell." But as one industry analysis noted, "the more you can do yourself, the less reason there is to collaborate." AI filmmaking can be isolating.
Impact on Creators
For filmmakers and VFX professionals, "As Deep as the Grave" establishes a reference case for how estate-approved AI performances can proceed within current legal boundaries. The combination of California AB 1836 compliance, SAG-AFTRA adherence, and family authorization represents the most straightforward path for posthumous AI work.
For creators working with AI video and voice tools, the production signals growing acceptance of AI-generated performances in mainstream film. The five-year production timeline (delayed by COVID, the 2023 strikes, and health issues) shows that even with AI, ambitious projects take time. But the core capability, building a convincing screen performance without the actor ever stepping on set, is now demonstrated at feature film scale.
The licensing and rights questions matter for any creator considering AI-generated characters or performances. California's laws apply specifically to recognizable real people, but the broader SAG-AFTRA framework for synthetic performers affects anyone producing content with AI-generated human likenesses.
Key Takeaways
1. "As Deep as the Grave" is the first feature film with a lead performance built entirely through generative AI, with no body double, stand-in, or prior footage from the production.
2. The production followed every available legal and union requirement: California AB 1836, SAG-AFTRA provisions, estate consent, and financial compensation.
3. The specific AI tools and companies involved have not been disclosed, a notable omission for a precedent-setting production.
4. Prior posthumous digital performances (Reed, Walker, Cushing, Fisher) all relied on body doubles with CGI face replacement. This is a different category.
5. The ethical template works for this case but may not generalize cleanly to less clear-cut situations where the performer's wishes are unknown.
What to Watch
The film is seeking distribution with a target 2026 release. How it performs commercially and critically will influence how quickly other productions follow. The audience response to a fully AI-generated lead performance, rather than the brief or supporting appearances seen before, will be closely watched.
Broader industry dynamics continue to shift. SAG-AFTRA's ongoing negotiations over AI provisions will determine the rules for the next contract cycle. The emergence of fully synthetic performers like Tilly Norwood raises separate questions about AI actors that are not recreations of real people. And as AI video generation tools from Runway, Google, OpenAI, and others improve, the technical barriers to this kind of production will continue to drop. "As Deep as the Grave" is the first. It will not be the last.
