Diary fiction has a long important history in gender politics; in recent decades the form has been adapted in various ways for feminist and post-feminist readerships, notably with the emergence of Chick Lit. My project will briefly sketch this history of gender politics and formal adaptation, then focus on the further and increasingly important problem of adaptation to the screen. If the diary tradition has been about women's (changing) voice, how can voice be shifted from the word to the image? I will examine this question through a study of one of the most beloved adaptations of a diary novel: Bridget Jones's Diary.
