Val Kilmer’s legacy has once again become the center of controversy after filmmaker Adam Marcus reignited criticism of the late actor with a series of explosive allegations.
Marcus recently faced backlash after describing Kilmer as “the worst human being” he had ever known, but he is refusing to back down.
The director, who worked with Kilmer on the 2008 film “Conspiracy,” insists his comments were not an attempt to attack a deceased star but rather a continuation of concerns he says he has publicly shared for years.
Adam Marcus found himself under fire after a social media post about Val Kilmer went viral.
In the post, the director alleged that Kilmer was frequently late, verbally abusive, physically aggressive, and often under the influence during production.
Marcus claimed the experience became so overwhelming that it almost pushed him out of the film industry entirely. According to him, the actor Kilmer “acted completely unprofessional” despite being paid $1.5 million for the project.
The reaction online was swift, prompting Marcus to remove the post from Threads. However, he told the Daily Mail he stands by every word.
“What I said about Val in that post was that he was the worst human I had ever met. That is true. There’s no hyperbole to that,” Marcus said.
The director maintained that his criticism was not new, noting that he had discussed his experiences publicly years before Kilmer’s death.
Kilmer Allegedly Changed Once Filming Began
Adam Marcus explained that his relationship with Val Kilmer started on a positive note. As a longtime admirer of the actor, he was thrilled to cast him in “Conspiracy” and described their early interactions as friendly and collaborative.
According to the 58-year-old, Kilmer even acknowledged rumors about his past behavior while assuring him he had changed.
“He said, ‘But I turned over a new leaf. I’m a new man,’” Marcus recalled. However, the director claims everything shifted once production moved to New Mexico.
“Day one of the shoot, he showed up three hours late to set,” Marcus alleged, claiming Kilmer was suffering from alcohol poisoning and required medical attention from an ambulance crew before filming could continue.
According to him, the late Hollywood star tearfully apologized and promised things would improve, but the issues allegedly escalated as filming continued.
Val Kilmer Accused Of Physical And Verbal Misconduct
One of Marcus’ most shocking allegations involves an incident he says occurred less than a week into filming.
“By day six, he showed up to set completely out of his mind,” he alleged. According to Marcus, Kilmer became fixated on showing off a new pair of Crocs.
When he asked him to wait while a shot was being prepared, he claims Kilmer kicked him in the crotch. “As I turned to my [director of photography], he kicked me in the crotch with his Crocs,” Marcus said.
Marcus further alleged that the “Top Gun” star repeatedly used a homophobic slur and directed it at him in front of cast and crew members.
He also claimed Kilmer made inappropriate advances toward women on set, including his wife and co-writer Debra Sullivan. Sullivan backed up those allegations, telling the Daily Mail, “He kept grabbing my a**.”
Kilmer’s Behavior Was Remembered Differently By Others
Not everyone involved with “Conspiracy” shares Marcus’ perspective. Actor Jude Lanston, who appeared in the film, said Val Kilmer was gracious during their scenes together and even went out of his way to introduce himself afterward.
“Honestly, working with him was amazing,” Lanston said. However, he also claimed he witnessed some of the behavior Marcus described.
“I saw how he treated everybody else,” he said, adding, “He kicked the guy in the nuts.” When asked about Marcus’ viral post, Lanston added, “Everything was true.”
Other cast members offered more measured reactions. Jennifer Esposito said she had a “fine” experience working with Kilmer and urged people to focus on living individuals accused of misconduct.
Christopher Gehrman also spoke positively about the actor, calling it “an honor” to work alongside him.
Val Kilmer’s Reputation Followed Him Throughout Hollywood
Marcus is hardly the first filmmaker to publicly criticize Kilmer’s behavior. Over the years, several high-profile directors shared stories about difficult experiences working with the actor.
“Batman Forever” director Joel Schumacher famously called him “childish and impossible,” while Oliver Stone told Rogerebert.com in 2025 that Kilmer’s “personality was not easy to get along with.”
Richard Stanley was even more blunt, saying, “I don’t like Val Kilmer, I don’t like his work ethic, and I don’t want to be associated with him ever again.”
Kilmer himself addressed the criticism during his lifetime. In a 2017 Reddit AMA, he suggested his reputation stemmed from his intense focus on acting.
“I only cared about the acting and that didn’t translate to caring about the film or all that money,” he said. In his 2021 documentary “Val,” the actor offered perhaps his most candid reflection.
“I have behaved poorly. I have behaved bravely. I have behaved bizarrely to some,” Kilmer said, further noting, “I deny none of this and have no regrets because I have lost and found parts of myself that I never knew existed. And I am blessed.”
