Also Star Wars… Star Wars even have a city covering an entire planet.

Imperial Officer: Lord Vader, the rebels have fled the ice planet of Hoth. After going to the swamp planet of Dagobah, Skywalker has rejoined his friends on the desert world of Tatooine. And now the rebel fleet is massing for an attack on the forest moon of Endor.
Darth Vader: I sense a great disturbance in the Force.
Imperial Officer: My lord?
Darth Vader: How else can so many worlds be totally covered with only one terrain type without regard to latitudinal variations?

If there is somewhere where humans can live, then likely there are also zones nearer and further from the poles.

So e.g. surely almost all planets with a livable zone would have polar ice caps.
