This thesis describes the use and importance of Kathak, North Indian classical dance, in commercial Hindi films. There is little information available on or analysis of dance in Hindi films, although it is an integral part of every commercial film. No other thesis has been written on the topic. This thesis establishes dance-related film genres and supplies relevant historical data. The influence of dance on women's role in film is also discussed. An appendix including film synopses, song and dance descriptions, and other relevant details is included as an aid to the reader. The research is based on primary source materials, particularly the author's interviews of film personalities and film viewing.
