Once Upon a Time... Space is a dramatic science-fiction TV series from 1982, running 26 episodes. It carries on from Once Upon a Time... Man, bringing back nearly all of that show's characters and recasting them in a science-fiction setting. Unlike the other entries in the franchise, it puts drama ahead of teaching, though a few educational moments remain, such as an episode about Saturn's rings. Several major galactic powers are locked in confrontation: the Omega Confederation, which counts Earth among its members; the military republic of Cassiopée, commanded by General Le Teigneux; and a mighty supercomputer at the head of a robot army. The story centers on Pierrot, son of Colonel Pierre and President Pierrette, and his friend Psi.
