High Noon in Space

That's how my dad described the 1981 science-fiction movie Outland with Sean Connery. I just saw it again on YouTube and for the life of me I don't understand why this movie isn't more well-known. I'm probably biased, but I just love it -- apart from the absurd claim that being exposed to vacuum makes people immediately explode. Maybe I shouldn't link it, but you can watch the whole thing here. My dad thought the chase/fight scene that starts around 48:30 was one of the best chase scenes ever filmed.
