Val Kilmer remains one of Hollywood's most memorable actors, celebrated for unforgettable performances in Top Gun, The Doors, Batman Forever, Tombstone and Heat. Even after stepping away from the spotlight due to health challenges, his resilience and passion for acting continued to inspire fans around the world. His legacy is once again drawing attention following the release of the first trailer for As Deep as the Grave, which uses groundbreaking AI technology to bring Kilmer back to the screen.

But before exploring that remarkable tribute, here is a closer look at the health battle that shaped the final chapter of his life.

Val Kilmer died on April 1, 2025, at the age of 65 in Los Angeles. His immediate cause of death was pneumonia as reported by PEOPLE, according to his daughter, Mercedes Kilmer, and his official death certificate. The documents also listed acute and chronic respiratory failure, squamous cell carcinoma at the base of the tongue, malnutrition, and a tracheocutaneous fistula as contributing factors.

Val Kilmer had been diagnosed with throat cancer as reported by PEOPLE around 2014–2015 and underwent chemotherapy, radiation, and a tracheotomy that permanently affected his voice and breathing. Although he later recovered from the cancer itself, the long-term complications left his respiratory system weakened and more susceptible to infections. He died at Ronald Reagan UCLA Medical Center surrounded by family and friends, and his body was cremated on April 7, 2025.

Despite those challenges, Kilmer's influence on cinema continues to live on and his latest screen appearance may be one of the most remarkable tributes to his career.

The first trailer for As Deep as the Grave introduces audiences to an ambitious historical epic while unveiling an AI-assisted recreation of Val Kilmer as Father Fintan. First shown at CinemaCon, the footage features Kilmer at multiple stages of life, from an older, ghostly figure to a much younger priest, making it one of the most significant uses of generative AI in a feature film.

Writer-director Coerte Voorhees told Variety that the role was always envisioned for Kilmer. Working alongside Mercedes Kilmer and the late actor's estate, the filmmakers used archived footage and generative AI technology to complete his performance while following union guidelines and ensuring the estate was compensated. With more than an hour of screen time, Kilmer's performance serves as a heartfelt tribute to the actor's enduring legacy.

Val Kilmer's final years were defined by extraordinary perseverance as he navigated serious health challenges without losing his love for storytelling. Now, As Deep as the Grave offers audiences one more opportunity to celebrate the remarkable talent and lasting impact of an actor whose legacy continues to resonate.
