Outland (1981) review

Titanium miners on Jupiter's moon Io keep having psychotic episodes and Federal Marshal O'Niel (Sean Connery), who's recently been assigned to maintain order, looks into the matter with medical assistance from snarky Dr. Lazarus (Frances Sternhagen), and it leads him to "company man" Sheppard (Peter Boyle), who is drugging his workers to make them "more efficient."  The set design - which reveals an advanced but rusty and corroded future - was most likely inspired by Ridley Scott's Alien, but it's basically tension-free and relies heavily on its sci-fi atmosphere until Sheppard sends in the mercenaries (a countdown clock appears on the screen) to take out O'Niel.  It also has this irksome black and white view of morality: out of thousands of people, there are only two good ones?  I'll say this about the markedly superior High Noon (which this is loosely based on): at least Grace Kelly was loyal....
