The effect a film can have on people was often used for political purposes. Even today, governments or regimes exploit cinema for their own purposes. Mostly it is about the justification of military action. Especially today, in times of digitalization and easy access to video cameras, verification of the authenticity of images is difficult. Photographs of protesters can be fabricated quickly and easily to suggest artificial unrest in a given area. Also, the opposite may be the case: For large demonstrations in the GDR era, masses of protesters simply disappeared from video recordings. In World War II propaganda films in Germany were the norm, castigating the Allied opponents as "rogue states" and propagating the German people's desire for "final victory" to stop the oppression.
