Mars doesn't really look like a fun place to be.
With less than a day left of a six month stint on Mars, a crew of astronauts decide to explore a pit. Unfortunately there's some kind of alien lifeforce that turns them into zombies, so they spend their last day on the planet trying to escape from each other's reanimated corpses.
It's difficult to think of a less convenient place to come under zombie attack; after all there's nowhere else to go. But zombies aren't the only reason to get off the red planet, and signs seem to indicate that Hollywood should never have gone there in the first place.
