For those unfamiliar, here's the background story:

Journalist Mark Kermode was interviewing director Herzog in 2005 on top of Lookout Mountain near Los Angeles, when suddenly he was shot in the abdomen by a random gunman armed with an air rifle of some kind. The suspect fled, but Herzog expressed no interest in pursuing him or reporting the incident and insisted on continuing the interview and that the projectile which had struck him was "not a significant bullet."

He describes the incident here in his own words around 6:10.
