“As Deep as the Grave,” which was previously titled “Canyon of the Dead,” is the true story of Southwestern archaeologists Ann and Earl Morris, chronicling their excavations in Canyon de Chelly, Arizona in their effort to trace the history of the Navajo people. Abigail Lawrie (“Tin Star”) stars opposite Tom Felton (“Harry Potter”), with a cast that includes Wes Studi and Abigail Breslin. Kilmer, or the AI generated version of the actor, will appear in “a significant part” of the finished film. The project uses both younger images of Kilmer, many of them provided by his family, and footage from his final years to show his character in various stages of his life. The audio also utilizes Kilmer’s voice, which, in his later life was damaged by a tracheal procedure.
