Abstract:The film Waterloo Bridge was under the background of war. The female protagonist Myra’s life is greatly altered and her fate begins to become tragedy. This dissertation will focus on analyzing the causes of the female protagonist Myra’s tragic fate from the following four aspects: the ruthless war, the weakness of her character, her concept of the supremacy of love and the criticism of social hierarchy. The ruthless war which leads to the couple’s separation has a crucial impact on Myra's fate. Myra’s weakness of character leads her to be reduced to a prostitute, which also has a significant influence on Myra's tragedy. Myra holds that love is supreme. This concept makes her feel that life is meaningless without Roy so that she commits suicide. And the overwhelming force of social hierarchy makes the couple separate. By the analysis of the female protagonist Myra’s tragic fate, the author hopes this dissertation can make readers know more about the female protagonist in the film Waterloo Bridge.
