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, perfectionistic and sometimes egotistical.
