I tweeted the same screenwriter earlier again about my guesses on what the visual references/images homages to Evangelion were in the trailer, and he liked that comment as well. I get the feeling that there might be quite a bit more in the actual film.
I have to say as well, there’s some striking imagery in this trailer. The wide shot of the elongated pyramid shape emerging from clouds in what I assume is the realm of the Cenobites, and the shot overhead of what looks like a gargantuan version of the Configuration covering half of the frame over the maze. For having what seems to be a small budget, this looks fairly ambitious from a visual standpoint.
