12 to the Moon

In the 1960 film 12 to the Moon, a dozen astronauts from different countries are sent on the first moon mission. They obviously didn't train together, as international tensions based on old stereotypes break out on the trip. On the moon, they suffer various accidents, injuries, illness, and death before they finally communicate with the moon beings, who tell them to go away but leave their cats. You will not be surprised that MST3K gave the movie a second life of sorts, in case you'd rather watch that version. (via Fark)
