Hamptons Doc Fest is back, and from December 4 to 11 will screen 33 feature-length and short documentaries at Bay Street Theater, Sag Harbor Cinema and, new this year, Southampton Playhouse, which hosts the closing night film, “Lost Wolves of Yellowstone.” This week, the editors talk to Jacqui Lofaro, founder and executive director of the Hamptons Doc Fest, about the festival’s 18th season and some of the highlights that are not to be missed.
