Acclaimed documentary maker Werner Herzog starts a three-part series on Channel 4 next week looking at the death penalty in the US.
Herzog, who opposes the death penalty, spent a year filming and interviewing death row inmates about their lives.
He focuses on the experience of living with the knowledge of how and when you are going to die.
The first portrait is of Hank Skinner, who was sentenced to death for murder 18 years ago.
He describes how he has had his execution scheduled three times, on one occasion having the last rites read to him and eating his final meal.
