Factual errors: The end of the movie shows a hypercube surrounded by eight cubes, one of which is the center of Flatland's Area 33H, which is surrounded by six squares. Continuing the analogy, each square should be surrounded by four lines, and each line should be surrounded by two points, yet in the actual Area 33H, each square is only surrounded by one line and each line is surrounded by only one point. Similarly, the other seven cubes in Spaceland do not appear to be surrounded by any squares, lines, or points.
