Neil Berkeley on 'Gilbert,' a quiet portrait of a loud-mouthed comedian

Documentarian Neil Berkeley spent seven months filming loud-mouthed comedian Gilbert Gottfried at home and on the road. He learned that Gottfried can squeeze a penny until it screams, and that off-stage, the bombastic Gottfried is a quiet, devoted family man. Berkeley tells KCRW's Matt Holzman about the risky strategy he used to make Gilbert -- filming the entire documentary even though Gottfried had not signed a release. And Berkeley explains how he funds his filmmaking through a day job as a graphic designer for TV shows like the Property Brothers and Real Housewives.
