It was only fitting that director Alex Gibney’s emotional documentary “Gonzo: The Life and Work of Dr. Hunter S. Thompson,” offering a refreshingly comprehensive perspective of the man and journalist, be narrated by friend and admirer Johnny Depp.

Johnny Depp previously portrayed Hunter S. Thompson in the 1998 Terry Gilliam film “Fear and Loathing in Las Vegas” and spoke somewhat awe-struck, somewhat bemused, of the experience and of his befriending Thompson.

Thompson made a name for himself in the 1960s, as a true wild child, a bona fide rebel and eccentric, as an innovator and as a troubled soul.

Thompson sought inspiration in drugs and alcohol, in doing things differently than expected by the establishment, in petting the cat against the grain as often as possible, in shooting guns, in being irrational, irreverent and unstable.

Hunter S. Thompson’s uniqueness made him an icon, a living legend, a role model, an idol. It also ultimately brought him disillusionment and this he put an end to by putting an end to his life.

It was his son Juan who found him slumped over his typewriter one afternoon in February 2005. He had died from a self-inflicted gunshot wound to the head. He was 67.

His funeral was financed for by Johnny Depp. Also attending the funereal ceremony were friends Bill Murray, Benicio Del Toro and Sean Penn.

Alex Gibney’s documentary, which premiered at the Sundance Film Festival in January, focuses on the major cornerstones of Hunter S. Thompson’s life, including his dichotomous relationship with the Hell’s Angels; running for sheriff of Aspen in 1970 (with slogans such as “It never gets weird enough for me”) and of course, pioneering gonzo journalism.

Johnny Depp narrates the documentary, produced by Graydon Carter.

Alex Gibney is no newcomer to the docu genre, as his 2007 documentary “Taxi to the Dark Side”, which told the story of an innocent taxi driver in Afghanistan who was tortured and killed at Bagram Air Force Base in 2002, received the Academy Award for Documentary Feature.
