Echoes That Remain combines hundreds of rare archival photos and previously unseen film footage with live action sequences shot on location at the sites of former Jewish communities in Czechoslovakia, Hungary, Poland and Romania. The film's production team spent over a year of research in archives around the world collecting film footage and photographs to help dramatize the folk stories, parables, and anecdotes. Playing an important role in the film are a series of evocative images from the famed photo biographer of Eastern European shtetl life, the late Roman Vishniac.
