In 'Dance on screen', renowned film maker Reiner E. Moritz explores how twentieth-century modern media influenced the development of dance, and vice versa. The invention of the film camera and television has allowed audiences to see not only beautiful dancing and wonderful choreography, but it also brought the dancers’ facial expressions and stage presence to the screen. These technical developments allowed this essentially ephemeral art form to be preserved. 'Dance on screen', about both classical ballet and modern dance, features interviews with recognized choreographers and directors. Moreover, many of the great dancers of the twentieth century are seen in performance, including Alvin Ailey, Anna Pavlova, and Pina Bausch.
