âEvery Time the Wind Blew,â a documentary on the Vietnam War, is scheduled to be filmed in Falmouth in October. The film is being co-produced by Susan P. Hunter, who grew up in Scituate and now lives in Nashville, Tennessee; and Wayne Soares, who grew up in Falmouth and now lives in Pittsfield. Ms. Hunter, the author of the book â77 Letters,â about her motherâs efforts to boost the morale of Vietnam War soldiers through writing letters, said the film is ânot necessarily going to be about the war itself, but rather the experiences that came out of that war.â
