'"Quigley Down Under" stars Tom Selleck [...] as an American sharpshooter who sails to Australia in search of work. A man named Marston (Alan Rickman) has advertised for a long-distance marksman, and Selleck is the best, able to hit targets so far away the camera can barely see them. Selleck is appalled, however, when he discovers that Marston wants to pay him to kill Aborigines. He throws the villain through the window, and starts a vendetta that only ends, of course, with an obligatory showdown in the corral.'
