Drug consumer par excellence, Hunter Thompson's legendary hallucinogenic and boozy escapades have by now been sufficiently documented, not to mention brought to pitch-perfect cinematic life by Terry Gilliam's 1998 adaptation of Fear and Loathing in Las Vegas. Less well known, however, is his lifelong political conscientiousness, which receives the lion's share of attention in Gonzo: The Life and Work of Dr. Hunter S. Thompson, Alex Gibney's (Taxi to the Dark Side, Enron: The Smartest Guys in the Room) loving yet even-handed non-fiction bio of the notorious father of Gonzo journalism. Narrated by Johnny Depp (Gilliam's Fear and Loathing star), and overflowing with archival footage and interviews with friends and enemies, the film lays out the vital details of its subject's life, from his outcast adolescence in Louisville, Kentucky to his suicide in 2005. Comprehensiveness, however, isn't necessarily the goal, and thus while most prime topics are tackled, the greatest focus is paid to Thompson's failed attempt to run for sheriff of Pitkin County, Colorado on a legalize-drugs platform, and his coverage of the 1972 presidential election, which resulted in the classic Fear and Loathing on the Campaign Trail '72.
