The animated movie titled "The Dot and the Line: a Romance in Lower Mathematics" from 1965 was directed by
Juck Chuck Jones, who is also known from animated cartoons like Bugs Bunny and Wile E. Coyote and Road Runner. The film retells the story of the book with the same title, which was originally written by American architect and children's book author Norton Juster.
The story details a straight line who falls in love with a dot. The dot, finding the line to be stiff, dull, and conventional, turns her affections toward a wild squiggle. The line, willing to do whatever it takes to win the dot's affection, manages to bend himself, giving rise to shapes so complex he has to letter his sides and angles to keep his place.
The movie won an Academy Award for Best Animated Short Film in 1966.
