This essay examine the femme fatal and the head character in the play Lulu Eine Monstretra gödie by Frank Wedekind. I have studied Lulu, who would be classified as a femme fatal, in terms to see what kind of woman’s portrait a femme fatal is. I will show with the theories of Judith Butler, Jacques Lacan and Joan Riviere how the femme fatal can be seen as a construc-tion, a role done by men. As well as a strong self owned woman. I will also discuss other con-cepts like femme-inism. My aim with this analysis is not to show one, but many different ways of looking at the femme fatal.
