A trailer has been released for the upcoming documentary about Hunter S.Thompson, the father of "Gonzo Journalism," and author of notable works like Fear and Loathing in Las Vegas. The film is led by director Alex Gibney and producer Graydon Carter and features narration by Johnny Depp. Thompson passed away in 2005.

The film addresses the major touchstones in Thompson's life-his intense and ill fated relationship with the Hell's Angels, his near-successful bid for the office of sheriff in Aspen in 1970, the notorious story behind the landmark Fear and Loathing in Las Vegas, his deep involvement in Senator George McGovern's 1972 presidential campaign, and much more.
