I've been looking at the concept of deep fakes after I heard about it on Joe Rogans Podcast. It does have some merit in the film and live broadcasting areas. Imagine being a german or Japanse and being able to watch a hollywood blockbuster in your home language without subtitles and the mouths are perfectly in sync. It will really do wonders for the movie industry in reaching and attracting new auidences. As for live translations it could make a world of difference when foreign delegates meet and need to translate between one another in order to have discussions.

Having said that we've seen the dark side of deep fakes with fake celebrity porn doing the rounds with Natalie Portman being one of them. Now we moving into an image and copywrite infringement and there lies damages and like you said creating propaganda films.

In order to combat things like these since the tech will only get better we will need render bots that can deconstruct film and the lacing over it in real time that way if the bot pics it up it can tag the video and content as deep fakes and also provide a link to the original content used. Giving users oversite and clarity. I'd also like it if we could hold people accountable for the deep fakes they make since they could have far reaching implications if the wrong message is placed on the wrong face at the wrong time
