Val Kilmer AI deepfake film As Deep as the Grave has just released its first trailer. The internet has responded with overwhelming disgust.

A widely recognised actor known for his roles in films such as Top Gun, Batman Forever, and Kiss Kiss Bang Bang, Kilmer died from pneumonia last April at 65 years old. Upcoming film As Deep as the Grave has now used generative AI to create a digital puppet in Kilmer's likeness, having it portray a character appearing in "a significant part" of the historical film.

As Deep as the Grave follows married archaeologists Ann Axtell Morris (Abigail Lawrie) and Earl H. Morris (Tom Felton), who conducted fieldwork in the U.S. southwest during the 1920s. Kilmer's AI-generated likeness will be used to depict Father Fintan, a Catholic priest who is also a Native American spiritualist. The film also features Abigail Breslin, Wes Studi, and Finn Jones.

Though Kilmer was cast in As Deep as the Grave prior to his death, delays in production and issues with his health meant he never shot any scenes. Kilmer had previously given a tech-assisted performance in Top Gun: Maverick, which digitally altered his real voice. He also worked with UK company Sonantic to create an AI speaking voice based on his old recordings. However, As Deep as the Grave will be the first time his likeness and voice will be completely AI-generated in a film.

"Very fitting that this trailer includes a scene where a corpse is unceremoniously yanked out of the ground," read one of the top comments on As Deep as the Grave's trailer at time of writing.

CGI likenesses of deceased actors have been used in feature films before. In 2016, Rogue One: A Star Wars Story gained attention for using CGI and motion capture to resurrect Peter Cushing and portray a younger Carrie Fisher for a few minutes of the film. In 2015, Furious 7 used similar techniques to insert Paul Walker into the remainder of the film after he died mid-shoot. Though Furious 7 largely received a pass due to the circumstances, Rogue One received criticism regarding the ethics of its CGI Cushing. Using generative AI to completely create a performance out of nothing appears to go a step even further, completely removing any actors from the process.

Writer and director Coerte Voorhees told Variety that he chose to use AI rather than recast the role due to budget constraints, and that Kilmer's children gave the project their blessing. Even so, online commenters have labelled it disgusting and disrespectful, not only for digitally reanimating Kilmer but also for the damaging precedent As Deep as the Grave's use of AI could set for the film industry as a whole.
