Armed with a boom microphone and video camera, documentary filmmakers Liz Wakehouse and Brent Werzner were recording a rehearsal for “Imagine That: Our Stories Take Flight!” at a New England Youth Theatre Production, says the Brattleboro Reformer. They have been filming classes and rehearsals of Theatre Adventure troupes since last fall, gathering footage for their documentary to be submitted to festivals this fall. The program offers classes for all ages and for mixed abilities.The group was founded seven years ago by Darlene Jenson and parent Laura Lawson Tucker because the community had limited options for after-school programs designed specifically for children with mental and physical handicaps. The skills they learn on stage often are transmitted to their “outside” lives.” If they learn to use a big, loud voice and articulate here, then that helps them to communicate out there, Wakehouse said.
