The Water Engine

Essential viewing for those of us who like David Mamet's highly stylised dialogue and his always watchable cast of regulars, but it's a shame that someone as sharp as he is, and an expert on con games too, should appear to endorse the apparently undying folk myth of the man (there have been several of them) who invents an engine that runs on water but is suppressed by big business. A film that accepted the falsity of free energy/perpetual motion claims and the villainy of the people who promote them - at least one free energy salesman is probably robbing the local farmers of their savings in a Midwest church hall right now - would have been a really ripe subject for Mamet, and a more satisfying film.
