The movie was forgettable -- as you can see, I can't remember it more than that; indeed, I don't think I actually ever saw it, but may have only read about it in a review -- but that line has stood out in my memory ever since.
Tell me a big, fat lie and make me believe it.
The world is full of religious leaders who believe in nothing but their ability to induce "faith" by their preaching. Their name is Elmer Gantry. And the world is full of politicians who believe in the same. They are the Voice of Saruman. (And, of course, there are those whose politics is religion, and vice versa.) Sellers of snake oil. Tribunes of the people who despise those they claim to lift up, purveyors of virtues they do not live by. Parasites -- and sometimes, predators.
There are Republicans like that. And there are Democrats like that. Over the years, I have noticed that Republicans are more likely to hold their Gantrys and Sarumans accountable than are Democrats -- but there are always examples one can point to if one wants to indulge in whataboutism.
The thing is, there are also always people who want to be told that big, fat lie. Who know or suspect that it's all fake, but they want to be made to feel that they're on the side of the angels when they give to or vote for these people.
In the end, we get the leaders we deserve. God help us.
