I'm reminded of "Wings of Desire". 1987, by the director Wim Wenders. Original German title translates out to The Heaven/Sky Over Berlin.
It's a gorgeous, gorgeous little contemplative film. It's about two angels who companionably hang out together, while they do their job of contemplating and recording what goes on on Earth. No humans but children can see them. From angel perspective, the world is in monochrome, and from human perspective it's in colour.
They sit around in peculiar places, like on top of lofty statues on obelisks. And they watch some mortals in particular. So it's the angels' story, and it's the story of some particular human people, as well as a story about the city of Berlin.
Eventually they meet a human who used to be an angel himself, but became mortal.
I'm not telling any more of the story, because I don't want to give away the ending.
If you think you know a film that sounds like this one, you'd be right. Wings of Desire has in part or in pieces inspired more than a few other movies since.
Personally I found Wings of Desire to be an intense and riveting movie, for one where very little happens in it. Also I fell in lust with one of the angels. But then I'm prone to do that.
Also, if you haven't seen A Fish Called Wanda, you suck and you need to remedy that.
