At one time, Val Kilmer looked to be most promising actor in Hollywood. And yet each and every director that the man has ever worked with probably has something bad to say about him, which has likely led to the state of his career nowadays. Which is - let's face it - barely a career at all. Nobody is willing to put up with his , apparently. Kilmer has his defenders, of course - those who believe he was, at one time, truly dedicated to his art, and his temper manifested as a result of his frustrations with incompetent filmmakers. He also might be slightly insane, given his panache for going a bit Gary Busey in interviews, which certainly hasn't help his image - and then there's all those ex-wives and former lovers who have gone on record to let the world know how nuts the guy might be. His most famous meltdown, of course, occurred during the making of Batman Forever, where Kilmer reportedly came to blows with Joel Schumacher. To be fair, given the state of the final product, I'm kind of with Kilmer on this one. Schumacher had to get something for the work he turned in. Screenwriter Kevin Jarre, who wrote Tombstone, said of Val Kilmer: "There's a dark side to Val that I don't feel comfortable talking about." He died at age 56, under "mysterious circumstances." Nah, not really - it was heart failure. I like to spice these things up with lies, occasionally. It's all for you. Like this article? Who have we missed? Let us know in the comments section below.
