Yes, "The Rum Diary" is based on a true story. The film is adapted from the novel of the same name written by Hunter S. Thompson, which was published in 1998, although it was originally written in the early 1960s. The story is semi-autobiographical, reflecting Thompson's experiences as a young journalist in Puerto Rico during the late 1950s. The film stars Johnny Depp as the protagonist, Paul Kemp, and captures the chaotic and hedonistic lifestyle of the time, intertwined with Thompson's distinctive voice and style.

No, "The Rum Diary" is not a prequel to "Fear and Loathing in Las Vegas." Both films are based on works by Hunter S. Thompson, but they are separate stories. "The Rum Diary," released in 2011, is set in the late 1950s and follows journalist Paul Kemp as he navigates life in Puerto Rico. "Fear and Loathing," released in 1998, is based on Thompson's experiences in the 1970s and follows Raoul Duke and Dr. Gonzo on a drug-fueled trip to Las Vegas. While they share thematic elements, they do not have a direct narrative connection.

"The Rum Diary," directed by Bruce Robinson and based on Hunter S. Thompson's novel, received mixed reviews from critics. The film stars Johnny Depp as a journalist in 1960s Puerto Rico, exploring themes of idealism and disillusionment. While some praised Depp's performance and the film’s vibrant visuals, others felt it lacked a cohesive narrative and failed to capture the spirit of Thompson's writing. Ultimately, whether it's considered "good" depends on personal taste, especially for fans of Thompson or Depp.

In "The Rum Diary," which was released in 2011, Johnny Depp was born on June 9, 1963. Since the film is set in the 1960s, he would have been around 47 or 48 years old during filming. Depp portrays Paul Kemp, a journalist navigating life in Puerto Rico. The film is based on Hunter S. Thompson's novel of the same name, capturing the tumultuous and often chaotic experiences of the character.
