War on Things (1998)

Ditto is an idealist. He does not, unlike Lina, his life companion, attach importance to the things around him. Lina, on the other hand, is captivated by objects and all her attention is focused on collecting them. One day all things revolt against Ditto. The objects complain to Lina that it is Ditto who mistreats them and Lina believes the objects. Ditto decides to turn himself into a thing to show Lina their true nature. However, the things are not malicious towards Lina. After a while, Ditto begins to understand that he has lost the war with things.
