The late actor's digital replica appears in a new trailer, marking the first major posthumous AI performance created with estate permission.
The trailer for As Far as the Grave opens with a familiar voice. Val Kilmer's distinctive rasp delivers a monologue about mortality. But Kilmer died in 2022. What audiences are hearing and seeing is an AI-generated replica, created with his estate's permission according to Euronews.
This represents a new phase in Hollywood's experiment with digital resurrection. Unlike previous posthumous CGI appearances that relied on body doubles and existing footage, the film employs what the production describes as advanced video AI techniques to generate entirely new performances. The estate's involvement distinguishes this from unauthorized synthetic fakes, positioning it as a test case for how the industry might handle digital performances after an actor's death.
The trailer shows little about the actual quality of the AI performance beyond brief glimpses. Kilmer appears in shadow for most shots, his face partially obscured. The choice could be artistic or could mask technical limitations. The voice work sounds more convincing than the visual elements, though compression artifacts in the trailer make definitive assessment difficult.
Previous attempts at digital resurrection have met mixed responses. Peter Cushing's CGI appearance in Rogue One required extensive manual animation. James Dean's planned but ultimately abandoned CGI casting in Finding Jack sparked industry backlash. What makes this case different is timing. Video AI capabilities have advanced significantly since those efforts, and the production has explicit estate cooperation.

The production has remained quiet about technical specifics. Euronews reports the use of video AI and other advanced techniques but provides no details about which models or methods were employed. The studio declined to specify whether they trained custom models on Kilmer's extensive filmography or used general-purpose video generation tools with careful prompting.
This opacity matters because it obscures both the technical achievement and the precedent being set. If the performance relies heavily on manual post-production cleanup, that's a different proposition than if AI systems can now generate convincing human performances with minimal intervention. The distinction affects everything from production costs to union negotiations about digital doubles.
The Screen Actors Guild has been wrestling with AI performance rights since before the 2023 strikes. Current contracts address digital replicas of living actors but leave posthumous use largely to individual estate agreements. Kilmer's case could establish a template, or serve as a warning, depending on audience reception and how transparent the production becomes about their process.
Estate permission may become the key differentiator between authorized AI performances and synthetic fake controversy. Technical details remain deliberately vague, preventing accurate assessment of the AI's actual capabilities. The trailer's strategic use of shadows and obscured shots suggests possible limitations in the facial generation. This marks a shift from CGI recreation, which required extensive manual work, to AI generation of new performances. Industry response will likely depend on both audience reception and how much human cleanup work was required.
The film releases next month, though no critics' screenings have been announced. Whether As Far as the Grave represents a breakthrough in AI performance or simply better marketing of existing techniques will only become clear when audiences can see the full performance beyond carefully selected trailer moments.
