Val Kilmer, who starred in films such as Top Gun, The Doors, and Batman Forever while earning a reputation as a Hollywood bad boy, has died, the New York Times reported. He was 65. The cause of death was pneumonia, the paper said, citing his daughter Mercedes Kilmer.

The California-born, Juilliard-trained actor was one of Hollywood’s most prominent leading men in the 1990s before numerous spats with directors and co-stars and a series of flops dented his career. Over the years, Kilmer gained a reputation as temperamental, intense, perfectionist and sometimes egotistical.

“When certain people criticise me for being demanding, I think that’s a cover for something they didn’t do well. I think they’re trying to protect themselves,” Kilmer told the Orange County Register newspaper in 2003. “I believe I’m challenging, not demanding, and I make no apologies for that.”

He made his film debut in the spy spoof Top Secret! (1984) before appearing in the goofy comedy Real Genius (1985). He then rocketed to fame as Tom Cruise’s co-star in the smash 1986 hit Top Gun (1986), playing naval aviator Tom Iceman Kazansky. Kilmer starred in director Ron Howard’s fantasy Willow (1988) and married his British co-star Joanne Whalley, with whom he had two children before divorcing.
