In the Blood (1989)
Whether or not you buy director George Butler's arguments about the sanctity of hunting big game in Africa (he insists that killing animals helps conservation), his second documentary on this list gives you an invaluable sense of the history of the sport that obsessed the likes of Ernest Hemingway. As the son of a game tracker, Butler relishes in taking his own son Tyssen on a three-week safari that mirrors the hunting expedition Teddy Roosevelt took with his child in 1908. Accompanying the filmmaker are two direct descendants of Roosevelt; Butler remarks that his group is connected to the former president "either by blood or by their admiration for him." The vintage footage is visceral, as is the sight of Tyssen bagging a water buffalo and a killer croc.
