Even Dwarfs Started Small (1970) by Werner Herzog
for patients who happen to be both mentally ill and dwarfs (although I suspect being the latter helps the powers that be characterise them as the former).There is a day on which all of the staff except one seem to be absent, and the one staff member on duty has an inmate, Pepe, tied up as some sort of hostage to good behaviour of the others.
The problem is that they simply do not seem to be concerned for his welfare. They have their freedom and they're going to enjoy it. It has to be said, he doesn't seem too worried, either: we see him frequently during the movie and he is generally smiling, and never says a word.
Oddly enough, although town is nearby and they have a vehicle, they never leave the environs of their insitution.Instead, they revel in their freedom. Some of what they do is kind of sweet, innocent even, like arranging for Hombre to get "married", which seems to be no more than putting him in a room with a woman (there is no account of what sort of feelings they might have for each other - this movie doesn't do backstory):
A lot of what they do is fairly harmless, like setting the vehicle to run in circles all day in the compound, and surf on top
or practice bull-fighting techniques with it
Not all is fun and games, however. There are two blind dwarfs, who are normally kept separate for their own good but today they're out with the others and are periodically tormented. I think its mostly in fun, like sneaking around them and taking some food
This is not a movie which comes to any sort of point or has any sort of lesson, save the simple celebration of freedom. Perhaps that is why Herzog saw fit to conclude the movie with the most unlikely of images
