After the death of actor Val Kilmer last year, director Adam Marcus, who worked with him on the 2008 film Conspiracy, published a now-deleted social media post attacking Kilmer. In the post, Marcus wrote that Kilmer was “the worst human being I’ve ever known” and said he would “speak ill of the dead,” dismissing the idea that people should not criticize someone after death. The posts referenced Marcus’s collaboration with Kilmer on Conspiracy and included accompanying comments and an image of the two together on that set, according to reporting by multiple outlets. Marcus also suggested that Kilmer’s behavior on his set would have led to cancellation if it had been as extensive as he described.

Other coverage notes that Kilmer had previously acknowledged acting in ways he considered poorly in a 2021 documentary about his life and career, while further mentions from the reporting cite past critical comments about Kilmer from other directors. The outlets also report that Marcus did not immediately respond to requests for comment. The story centers on Marcus’s negative remarks rather than any publicly detailed incident.
