Kathryn Merteuil (Amy Adams)

A prequel to the original film shows a younger Kathryn. She also has a deceptive appearance, and is president of the banned Manchester Tribunal behind closed doors. She once again uses her powers of manipulation to control the situation, and it is revealed it is she who manipulated Sebastian into the cruel incarnation seen in the first film. This film focuses on when Sebastian and Kathryn's characters first meet, and their pleasure from plotting to destroy and seduce each other. She is still as devious, even threatening the vice-principal to do whatever she wants, otherwise she will go to the School Board and tell them he seduced her last summer when actually it is she who seduced him. In this film, Kathryn doesn't appear to have a cocaine addiction.
