Adam Marcus claimed Val Kilmer was the “worst human being” more than a year after he died from pneumonia.
The director, who worked with the late Batman Forever star on the 2008 action thriller Conspiracy, criticized Kilmer in a now-deleted thread over the weekend.
“#MicroIntellectMonday to the day you directed that guy. The guy who played Iceman and Doc Holliday (sic). You know it,” he wrote, along with a photo of himself and Kilmer, according to Entertainment Weekly.
“This is me and the Putts working on the set of ‘Conspiracy,'” Marcus, 58, added.
The filmmaker then addressed fans who were upset by his negative comments about the late “Top Gun” star.
“And for those who roll their eyes at the words ‘don’t speak ill of a dead bull,’ oh well,” he wrote, which was later reportedly deleted.
Marcus added that if Kilmer “had only done a tenth of what he did on my set today, it would have been canceled immediately.”
“The worst human being I’ve ever known…and that’s really saying something,” he concluded.
Kilmer played William “Spooky” McPherson, a disabled special operations Marine injured during combat operations in Iraq, in Marcus’ film.
When McPherson visits a friend in the southwestern United States, he discovers that his friend has disappeared and no one will admit that the person lived there.
Kilmer has previously been said to be difficult to co-star in films with.
In a 1996 interview with Entertainment Weekly, Batman Forever director Joel Schumacher said Kilmer was “childish and impossible” and “mentally disabled.”
“The Island of Dr. Moreau” director John Frankenheimer vowed never to work with Kilmer again after the 1996 horror film.
In a 2021 documentary about Kilmer’s life, the “Heat” actor addressed allegations about his behavior on set.
“I’ve behaved badly, I’ve acted brave, I’ve behaved in ways that are strange to some people,” he said. “I don’t deny any of this and I don’t regret it, because I lost and found a part of myself that I didn’t know existed. And I’m blessed.”
Kilmer died of pneumonia at his home in Los Angeles in April 2025. He was 65 years old.
The “Tombstone” star was reportedly bedridden in the years before his death due to lack of energy due to past cancer treatments.
