This thesis has the purpose to analyze two theatrical strategies in Top Girls by Caryl Churchill: the overlapping dialogue and the doubling characters. Churchill, a British woman playwrighter and socialist feminist, regards a theatre itself as a model for the ultimate change. She tries using the theatrical apparatuses to open the audiences mind to the women’s problems along with race, social hierarchy and class. In Top Girls, Churchill introduces women’s unique way of communicating to show women’s inability to sympathize with each other and the subject of the power to draw the audiences’ attention in the verbal chaos. She also uses the doubling characters to reveal the true image of top women in the society and history. They have suppressed the lower class women in order to succeed. Churchill thinks the suppressed women in the society have a potential to act bravely to overthrow the status-quo. These apparatuses play a pivotal role to show the limit of Theacherian successful women and encourage the audience to open the eyes to the possibility of women of all classes being successful, which is the driving force to transcend class differences among women.
