I've seen it

Not kidding. I work in a transcription company and this was one of our projects. The file had some missing scenes though, because it was in a very raw state and those scenes had to be reshot. But I got most of the story, and I don't want to spoil anything but I'd say it's quite similar to The Great Gatsby.

From what I've seen it looks like a decent movie. I'd love to see it in full when it comes out.
