Quigley Down Under (1990)

A skilled marksman from Wyoming travels to Western Australia to seek work from a man that he's not met. The man with the modified rifle is Tom Selleck. The prospective employer is Alan Rickman, One of them is noble and guided by morals; the other definitely isn't. A third player, a woman (Laura San Giacomo) who's a little crazy gives the stranger in a strange land scenario a welcome level of pathos that it might not have had otherwise.
Along the way we meet Australia's Indigenous people and the British army; the former group do a much more convincing job than the latter, who are used mostly to flesh out the political climate of the era (the 1860s). The film is generally high-spirited, but has a few serious themes from time to time.
