Written in 1959, well before the iconic Gonzo journalist developed his freewheeling style, the movie marks Johnny Depp's return to his favorite author's work. He played Thompson in the controversial 1998 film adaptation of his 1971 Fear and Loathing in Las Vegas and provided a heartfelt narration to Alex Gibney’s 2008 documentary Gonzo: The Life and Work of Hunter S. Thompson following the author’s 2005 death.
The film stars Richard Jenkins as the newspaper editor, Amber Heard as the love interest and Aaron Eckhart as her boyfriend. Here's the official GK Films synopsis:
“The Rum Diary tells the increasingly unhinged story of itinerant journalist Paul Kemp (Depp). Tiring of the noise and madness of New York and the crushing conventions of late Eisenhower-era America, Kemp travels to the pristine island of Puerto Rico to write for a local newspaper, the San Juan Star, run by downtrodden editor Lotterman (Jenkins). Adopting the rum-soaked life of the late-’50s version of Hemingway’s “The Lost Generation,” Paul soon becomes increasingly obsessed with Chenault (Heard), the wildly attractive Connecticut-born fiancée of Sanderson (Eckhart), a businessman involved in shady property development deals.”
