Prolific Hollywood actor Val Kilmer died on Tuesday at the age of 65, and amid the many condolences and tributes came a renewed interest in the details of his 2020 memoir.

One particularly tragic revelation in Kilmer's book was that he hadn't been romantically involved with anyone over the prior two decades and that he was "lonely" each day despite his immense fame, according to the Daily Mail.

Part of the reason for Kilmer's admitted loneliness was a particularly bitter and expensive divorce in the mid-1990s, followed a few years later by an especially "painful" and heartbreaking end to the last significant relationship he'd been involved in.

A rough love life

Per the Daily Mail, Kilmer married actress Joanne Whalley in 1988, and the celebrity couple had two children, a daughter named Mercedes and a son named Jack, before they were divorced just eight years later in 1996 for "irreconcilable differences" amid "constant rumors" of his infidelity.

The actor once remarked that the divorce, which occurred just a few months after Jack was born, was the "second most expensive in New Mexico," where he lived in Santa Fe for many years.

Still a huge star at that time, Kilmer dated several prominent leading ladies during his day, including women like Cindy Crawford, Angelina Jolie, Cher, and Daryl Hannah.

"I am lonely part of every day"

In his 2020 memoir, "I'm Your Huckleberry," Kilmer wrote that the 2001 break-up with Hannah, his last real romance, was "by far the most painful of all."

"I knew I would love her with my whole heart forever and that love has lost none of its strength," he continued of her. "I am still in love with Daryl. When we finally broke up, I cried every single day for half a year."

"I haven't had a girlfriend in 20 years. The truth is I am lonely part of every day," Kilmer confessed in his book. "I've always found women infinitely more interesting than men. Perhaps that's why we've always gotten along. We are big oafy elephants ... and they are butterflies."

A decades-long acting career

According to The New York Times, as confirmed by his daughter Mercedes, Val Kilmer died in his hometown of Los Angeles, California, on Tuesday at the age of 65 from pneumonia.

Born and raised in L.A., Kilmer studied acting as one of the youngest students ever enrolled at the prestigious Juilliard School in New York, and his career in the entertainment industry began on a Broadway stage in the early 1980s, though it didn't take long for him to become a Hollywood superstar with a plethora of leading and supporting roles on the Silver Screen.

Per his IMDb page, Kilmer was credited with appearances in 103 films and TV shows, with his first big hit coming in 1986 with "Top Gun."

Other memorable roles for the actor included his uncannily similar portrayal of rock star Jim Morrison in "The Doors," his iconic rendition of Old West legend Doc Holliday in "Tombstone," and his turn as the Caped Crusader in "Batman Forever," among many others.

One reason that so many of Kilmer's roles were unforgettable for his fans was his style of method acting, in which he fully embraced the character he portrayed for the duration of the project, which produced incredible results on the screen but also made him an exceptionally difficult and eccentric actor for his colleagues, directors, and producers to work with.
