Does it follow Todorov's theory?
This film does follow Todorov's theory vaguely. The new equilibrium is at the beginning where Walter Neff is telling the story to Keyes. Then the disruptive event comes when Walter Neff meets Phyllis Dietrichson for the first time. Recognition of the distruption could be considered when they have murdered her husband, and have to be cautious. When they attempt to repair the damage, by Walter going to see Phyllis and kills her. Then they return to the equilibrium, when Walter Neff is free of the femme fatale, and just has to confess the crime to Keyes.
