Flatland: The Movie is a 2007 American animated science fiction short film directed by Dano Johnson and Jeffrey Travis.

The story is based on the 1884 science fiction novella Flatland: A Romance of Many Dimensions written by Edwin A. Abbott.

Hex and Arthur discuss the laws of inheritance: how each new generation of Flatlanders, beginning with triangles, gains a new side until the shapes become indistinguishable from circles.

They also discuss how a citizen's shape affects their job, with triangles performing menial labor and circles ruling Flatland in the priest class.

They witness a cruel incident where a Circle Priest arrests a slightly irregular octagon child, prompting Hex to yet again wonder what happened to her pentagonal parents.

The head circle ruler of Flatland, Pantocyclus, issues a new edict that bans discussion of heretical topics such as a third dimension or the ruins at Area 33H.
