Most of these film-makers started as directors on the late 19th century stage, and likewise most film actors had roots in vaudeville or theatrical melodramas. Visually, early narrative films had adapted little from the stage, and their narratives had adapted very little from vaudeville and melodrama. The workplace is highly varied, and actors need to be flexible with regard to where they work and the type of environment they work in. Those prepared to work in all kinds of different situations and who are able to adapt to their different environments will be more successful in finding their niche.
