'Once in a New Moon' is an old English film with the atmosphere of an Ealing comedy. A dead star comes near our planet and its gravity sucks an English village into space so that it orbits Earth as another moon, complete with gravity, atmosphere and a sea. I would class it as a fantasy rather than science-fiction because the circumstances are impossible.
That carping aside, it's great fun. Cut off from the rest of humanity, the occupants of Shrimpton-in-Space have to husband their resources and find a way to survive. They form a microcosm of the England of the time including the class system and it's likely that events would unfold this way in real life if the unlikely circumstances came to pass. Given that it was written in 1935, before World War II, socialism is given a reasonably fair hearing though the agitator who tries to set fire to his Lordship's mansion isn't nice.
Perhaps English people really were this nice and reasonable once and perhaps they can be again. Don't hold your breath.
