Scene 1: In the beginning of the film, Katniss ventures out to go hunt and bring back food for her mother and sister.
Katniss seems to be a matriarch of the family, and in doing so she is undergoing somewhat of an “inverse Oedipus complex”. This is explained using Freudian psychoanalysis. Rather than wanting the kill the mother and marry the father, the opposite is true. This is exemplified as she is scolding her mother, calling her “weak” because of her father’s death. Later on in the film, Katniss hallucinates the vision of her father walking into a mine and seeing him die in the collapse. This happened before she was able to work her way through the Oedipus complex, therefor she went through the inverse.
This scene can also be supported by a feminist perspective. Generally, the man of the family is expected to be the strong one while providing for the family, but in this case Katniss is the emotionally strong one and provides food for her family.
Scene 2: Katniss climbs a tree
During the Games, Katniss decides to climb a tree as she hears opponents coming her way. Psychoanalysis incorporates different personality traits such as the Id, the Ego, and the Superego. Katniss climbing the tree is an example of her ego at will. The Ego has no concept of right or wrong and acts only to satisfy. Her quick decision to climb the tree was an act of satisfying her own interests. Other opponents in the game use their Egos to team up, kill, hide, etc. Later on in the Games, Katniss decides to help the youngest competitor, Rue. This is Katniss’s Superego acting. The Superego serving a moral purpose, this was Katniss’s way of doing good for someone within the games.
