Films.

Films was seen more as a means of relaxation than directly for explicit propaganda purposes. 

The number of flimgoers quadrupled between 1933 and 1942. The state over time increasing got control over both film companies and the content of films. The government left 4 major film companies to stay private because they didn't want to effect or harm the amount of export sales. However, the RMVP gradually brought up shares, and increasingly financed films, so indrectly comapnies became state owned. In 1942 all were nationalised under Ufi (Ufa Film GmbH)

Several American films were banned in Germany. 

Goebbels personally looked over each film broadcasting in Germany to see it was fit for German citizens to watch. For example if it was 'politically and artistically valuable', 'culturally valuable', a 'film of the nation', 'valuable for youth' - and given money accordingly. During the Nazi regime over one thousand feature films were produced. With one-sixth bein overtly propagandist. 

Leni Riefenstahl a producer was in charge of get detailed recording rallies and festivals, to tell/explain to people what's happening. Her most famous films were 'Triumph of the Will' about the Nuremberg Rally and 'Olympia' about the 1936 Olympic Games in Berlin.

Films were probably more effective in keeping support for the regime than in indoctrinating people with Nazism. The need for entertainment took priority.
