The movie maker concluded his post by writing: “Worst human being I’ve ever known … and that is really saying something.”
Kilmer was previously criticised by his Batman Forever director, Joel Schumacher, in an interview with Entertainment Weekly back in 1996 with the movie maker branding the actor “childish and impossible” and suggesting he was a “psychologically disturbed human being”.
The Island of Dr. Moreau director John Frankenheimer also declared he would never work with Kilmer again after they wrapped the 1996 film.
However, Kilmer rebutted both directors’ comments in a 2003 interview with Rolling Stone, saying: “I’ve been careless about how I viewed my business.
“But I trust that the truth is the truth and a lie is a lie. Frankenheimer, bless him, he passed on, but he had a history of being mean about people …
“Schumacher’s not a great director by any stretch, but he makes everyone happy, he makes money. But his version of me being unstable – he’s very smart, he can’t say anything about work, because then I can sue him for slander.”
Kilmer also addressed his issues with past work colleagues in his 2021 documentary, Val, admitting: “I have behaved poorly. I have behaved bravely. I have behaved bizarrely to some.
“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.”
