Here's the trailer. You'll see the quality of the filmmaking, but other than that it doesn't even begin to do the movie justice. It's all a collection of short shots edited together. But as I said, the movie is not that. It's done in what looks like a fluid three or four shots without cutting.
Better perhaps is this four-minute "behind-the-scenes" featurette on how they made the thing. Just from this small bit, you'll get at least a sense of the undertaking and how richer the film is than it appears in the ads or trailer.
Also based on true events, it tells the story of an Austrian farmer who is a conscientious objector, refusing to fight for the Nazis in World War II, and how that all impacts his life and family, in his neighborhood and prison. And also the importance that such hidden lives by unknown people help create in the fabric of life. How long ago Mallick began planning the film, I don't know, so it's hard to tell how much of it might have been inspired by the resistance to Trump, or if that's an overlay that audiences may bring to it. The film really is beautifully done, though, and I enjoyed it, just…loooooooooong.
