A list of some propaganda films with links to watch.
1) Reefer Madness. One of the most interesting propaganda films ever made, a mix of strange bureaucratic skills and folk science https://www.youtube.com/watch?v=zhQlcMHhF3w
2) A U.S. propaganda film post WW2. The U.S. had some facts to work with, not a bad film, but the focus was "we are good, they are bad", rather than "look at what people do". https://archive.org/details/DeathMills
3) A U.S. propaganda film about Vietnam. If any person can watch more than 10 minutes of it they have a gift, a high tolerance for propaganda. The premise seems to have been 'find a skilled movie maker and pay him to pump our story'. Hint...they should have offered more money. Lots more. Or something. https://spiegelman.tumblr.com/post/37115898834/the-last-film-ever-produced-by-the-legendary-john
4) Perhaps the most famous propaganda video of all time, Triumph of the Will https://www.dailymotion.com/video/x6uajey is usually presented as a strictly Nazi video, but in fact it is a summary of the history of industrialization and globalization.
