Flatland the Film is an animation that has been heralded as a masterpiece (Phil Hall review at http://www.filmthreat.com), and so it was with high expectations that I came to view the DVD signed by the animator who single-handedly created the imagery. In the age of Pixar, Flatland the Film is unusual in being an independently produced feature-length computer-generated animation. It is an adaptation of Edwin A. Abbott's Flatland: A Romance of Many Dimensions (1884); such has been the staying power of this novella that the most recent edition was issued in 2006. Ladd Ehlinger's animation, the fourth animated adaptation of Abbott's writing, draws extensively on the novella and thus is informed by Abbott's knowledge of the landscape of mathematics and theology in the latter half of the nineteenth century.

Ehlinger's animation follows the novella in being divided into three sections in which we are introduced by the character A Square to the dimensional and social organisations within Flatland the Film. First we see the two-dimensional Flatland itself; then we are offered a one-dimensional world via A Square's dream of his visit to Lineland; finally, we encounter the three-dimensional world of the visiting character A Sphere: Spaceland. Throughout these sequences we are treated to mathematically inclined explanations of the various orders of dimensionality. For those interested in the consequences of perspective these moments can be compelling, but for the non-mathematically inclined they painlessly flow by, though sometimes for a touch too long. In addition to the maths, the various dimensional encounters also introduce their differing social organisations, with the purpose of revealing a central concern of Flatland: the conflict that ensues when different ways of knowing the world confront established belief systems or commonly held views of the world.

Animation is ideal for allowing a filmmaker to visualise dimensionalities that could not be experienced in the actual world, or even easily rendered using live-action techniques. Flatland the Film opens with a brief suggestion of a Flatlander's visual perspective (a line). In the guise of A Square giving his son a lesson in 'sight recognition', a single vertical line appears on the screen. This is accompanied by a series of questions:

Q: What do you see when you look at me?

A: A Square.

Q: Is that what you really see?

A: Um ... A line.

Q: Is that all?

A: Um ...

As this dialogue continues, the brief glimpse of the Flatlanders's perspective gives way to an overhead view of A Square and his son, but we learn from the voiceover that Flatlanders know shape through a nuanced reading of the shading of the single line that they actually see. Luckily viewers are able to know the various...
