At the Titanic Historical Society convention in 1997 on the Queen Mary, a movie was shown containing left-over footage from the making of Cameron's film--specifically, footage of the interior sets as water was entering, plates floating off the tables . . . that kind of thing, all set to period music including Songe d'Atomne (spelling?) and Nearer My God to Thee. Does anyone know if this movie was ever made available for public purchase?
