A year before his death, Bill Hicks appeared on the David Letterman show. Letterman judged his segment to be substandard and so cut it from the subsequent show. He did not know that Hicks was dying of pancreatic cancer at the time. 15 years later, in January 2009, Letterman invited Hicks's mother Mary onto the show as a belated form of apology.
The co-directors had only 800 photos of Hicks to illustrate their story. They found to their surprise that there was virtually no filmed interview material of Hicks simply talking about himself and his background.
