Filmmaker Christoph Gelfand's new work explores the collective sorrow of Bill Buckner and the Red Sox' loss in the '86 world series. Gelfand combines that painful moment with his own dashed childhood dreams of victory on a playing field. The result is a philosophical journey about acceptance and forgiveness. We'll talk with Christoph about "Chasing Buckner" in advance of its premier this weekend at the New Hampshire Film Expo in Portsmouth.
