Watch Chronopolis

Chronopolis is a Polish 1983 drama, with French collaboration. It features animation and computer-generated special effects, the ones available at the time. Chronopolis is a giant city that's populated by giants and people who pass themselves as explorers of the environment around them. The city is set up in the sky, and the people have become immortal. But they're tired of having forever life. They spend most of their living moments building strange and impractical items which have little to no purpose to them. In the process, they eagerly and patiently await for the most prized present to fall into their laps.
