Quigley Down Under (1990)

Synopsis
Tom Selleck stars as American cowboy archetype Matthew Quigley in Simon Wincer's outback western Quigley Down Under. Answering an advertisement placed by Australian cattle baron Elliot Marston (Alan Rickman) to come to the rugged and uncivilized Australian countryside and shoot dingoes, Quigley finds himself halfway around the world, only to find that Marston wants to exploit his talents as a sharpshooter in order to wipe out the Aborigine population. Taken aback by this square-jawed genocide, Quigley grabs Marston and hurls him through a window. Marston, who controls the region, sets out to hunt Quigley down. But helping him stay one step ahead of Marston is the addlebrained expatriate American trollop Crazy Cora (Laura San Giacomo) who insists that Quigley is her husband Roy. ~ Paul Brenner, All Movie Guide
