I've been involved in doing advertising for various elections and I just couldn't see doing anti-Trump advertising in this election. My line has been, "How could you do anything worse that what he does himself?".

What's great about documentary genre, it seems to me, is that it can be experimental filmmaking. You have a license to do a lot of diverse things under the umbrella of "documentary."
