Released 50 years ago this month, Deliverance is one of those films that, once seen, is hard to forget.
Starring Jon Voight and Burt Reynolds, it's a work that reveals the horrors that human beings are capable of when their very survival is at stake.
A half century later, it remains a screen classic, oft-imitated, rarely bettered.
For RTÉ Arena, director John Boorman discusses the legacy of his film - listen above.
