Pointillism represents the time-consuming nature of the ballet and the aim for perfection, themes which are both explored throughout the 'Black Swan' movie. The film itself, is remarkably grainy, which is reflected in thousands of small dots that illustration is made of.
The style is inspired by Art Deco and Constructivism. Art Deco references the motherland of ballet, France, where the style has its' roots. Russian constructivism links to the famous Ballets Russes (which have brought the ballet back in Europe in the beginning of 20th century) and Tchaikovsky's original Swan Lake ballet.
Soundtrack by Clint Mansell, filled with piercing and creaking sounds mixed in Tchakovsky's classic, was also a big influence both on the style and the technique.
