I'd recommend watching the movie without reading or watching the trailer, that way you can get immersed in it without any spoils. Then I would watch the interview, posted down below, with the director and actor to get their perspective.
An amazing film that touches a deep part of our experience, something that could possible happen to us. I don't want to give away anything!
