The film being a popular medium must be good entertainment if it is to be good propaganda. A film which induces boredom antagonises the audience to the cause which it advocates. For this reason, an amusing American film with a few hits at the Nazi regime is probably better propaganda than any number of documentaries showing the making of bullets, etc.
This leads to the further consideration that film propaganda will be most effective when it is least recognisable as such. Only in a few rare prestige films, reassurance films and documentaries should the Government's participation be announced.
