The Canadian-made documentary about how a man, mauled by a grizzly bear, puts together an anti-grizzly suit to find out why the bear did it - and which inspired the episode where Homer puts together a bear-fighting suit after his own mauling - will be coming out on DVD this summer from the National Film Board of Canada:
