The head of the film department, like Goebbels himself, could suggest ideas and themes, commission scripts and with all the means at his disposal support films that for example served military or foreign policy interests. He and Goebbels were also entitled to clean up "mistakes of taste" and "artistic errors" and to stop unpopular film projects altogether. After the revision of the Reich Film Law in 1934, the "violation of National Socialist, moral or artistic sensibilities" was included as a reason for prohibition. Every film project had to be approved before filming began, after the Reich film dramaturge had checked the script.[citation needed]
