Fear and Loathing in Las Vegas is a 1998 American stoner road black comedy film adapted from Hunter S. Thompson's 1971 novel of the same name. It was co-written and directed by Terry Gilliam, and stars Johnny Depp and Benicio del Toro as Raoul Duke and Dr. Gonzo, respectively. The film details the duo's journey through Las Vegas as their initial journalistic intentions devolve into an exploration of the city under the influence of psychoactive substances.

Hunter Stockton Thompson was an American journalist and author. He rose to prominence with the publication of Hell's Angels (1967), a book for which he spent a year living with the Hells Angels motorcycle club to write a first-hand account of their lives and experiences. In 1970, he wrote an unconventional article titled "The Kentucky Derby Is Decadent and Depraved" for Scanlan's Monthly, which further raised his profile as a countercultural figure. It also set him on the path to establishing his own subgenre of New Journalism that he called "Gonzo", a journalistic style in which the writer becomes a central figure and participant in the events of the narrative.
