Frontline's “Syria Behind the Lines”

Olly Lambert, writer/director/producer, discusses his Frontline documentary “Syria Behind the Lines.” Lambert is the first Western filmmaker to spend an extended period living on both sides of Syria's war—and to document, on camera, the realities of everyday life for rebels, government soldiers and the civilians who support them. “Syria Behind the Lines” airs Tuesday, April 9, at 10 p.m. on PBS.
