When organists or pianists used sheet music, they still might add improvisatory flourishes to heighten the drama on screen. Even when special effects were not indicated in the score, if an organist was playing a theater organ capable of an unusual sound effect, such as a "galloping horses" effect, it would be used for dramatic horseback chases.
By the height of the silent era, movies were the single largest source of employment for instrumental musicians (at least in America). But the introduction of talkies, which happened simultaneously with the onset of the Great Depression, was devastating to many musicians.
ActingSilent film actors emphasized body language and facial expression so that the audience could better understand what an actor was feeling and portraying on screen. Much silent film acting is apt to strike modern-day audiences as simplistic or campy. The melodramatic acting style was in some cases a habit actors transferred from their former stage experience. The pervading presence of stage actors in film was the cause of this outburst from director Marshall Neilan in 1917: "The sooner the stage people who have come into pictures get out, the better for the pictures." In other cases, directors such as John Griffith Wray required their actors to deliver larger-than-life expressions for emphasis. As early as 1914, American viewers had begun to make known their preference for greater naturalness on screen.
In any case, the large image size and unprecedented intimacy the actor enjoyed with the audience began to affect acting style, making for more subtlety of expression. Actresses such as Mary Pickford in all her films, Eleonora Duse in the Italian film Cenere (1916), Janet Gaynor in Sunrise, Priscilla Dean in Outside the Law and White Tiger, and Lillian Gish and Greta Garbo in most of their performances made restraint and easy naturalism in acting a virtue. Directors such as Albert Capellani (a French director who also did work in America directing Alla Nazimova films) and Maurice Tourneur insisted on naturalism in their films. Tourneur had been just such a minimalist in his prior stage productions. By the mid-1920s many American silent films had adopted a more naturalistic acting style, though not all actors and directors accepted naturalistic, low-key acting straight away; as late as 1927, films featuring expressionistic acting styles, such as Metropolis, were still being released. Some viewers liked the flamboyant acting for its escape value, and some countries were later than the United States in embracing naturalistic style in their films. Just as today, a film's success depended upon the setting, the mood, the script, the skills of the director, and the overall talent of the cast
