In the movie Castaway, Chuck Noland, played by actor Tom Hanks, creates an imaginary companion from a Wilson soccer ball, by painting his own bloody handprint into the shape of a face, and then naming him Wilson.
Chuck’s traumatized psyche exploits the resources immediately available to him, to restore some semblance of normalcy and emotional balance, giving him the wherewithal to survive his predicament. The soccer ball and Chuck’s own blood were the most accessible mediums for creating his temporary, anthropomorphic companion – a split off portion of his own psyche, projected onto a red faced soccer ball. If something more human appearing had been available, such as a puppet or doll, he most likely would have chosen that over the bloody soccer ball.
