Bing Liu on his coming-of-age documentary, ‘Minding the Gap’

For director and cinematographer Bing Liu, growing up in post-industrial Rockford, IL, was no picnic. As a teenager obsessed with skateboarding, he started filming two of his skater friends, and eventually himself, as they moved through a difficult adolescence in a hard-luck town. Over the course of years, Liu realized he had a powerful coming-of-age story on his hands. Liu tells KCRW’s Matt Holzman about following his friends and their fractured families--camera in hand--to make the Sundance award-winner ‘Minding the Gap,’ which is now available on Hulu.
