This thesis examines the multiple factors which have influenced costume design in film history by observing the various representations of the historical figure Cleopatra in motion pictures. Beginning with a brief history of the changing role of the costume designer in film, and a brief history of both the historical and legendary Cleopatra, this paper then analyzes the factors that have influenced costume design in four specific films about Cleopatra: Cleopatra (1917), Cleopatra (1934), Caesar and Cleopatra (1946) and Cleopatra (1963). Criteria for examination of costume design in these films includes previous precedents and contemporary screen conventions, the background and style of both the director and costume designer, the ramifications of the Motion Picture Association Code, studio influence and trends of contemporary fashion. Transcribed drawings of the various costumes which appear in the aforementioned films of Cleopatra, and still photographs from these films are included to supplement written observations. / Master of Fine Arts
