However, there may be an extended cut. Spoilers ahead.
In a recent interview with Collider (embedded below) Scott talked about the cut and deleted scenes.
The Blu-ray will have about 30 minutes of deleted scenes (he mentions one where Noomi Rapace’s fight with the Engineer is longer) and the extended cut may be 20 minutes longer, but he is not sure whether to do it or not.
You’re going to do an extended cut on the Blu-ray/DVD. Is it a lot longer?
SCOTT: Twenty minutes.
So there’s, like, twenty minutes that will be added back in for a longer version?
SCOTT: Maybe. But I’m so happy with this engine, the way it is right now. I think it’s fine. I think it works. It can go in a section where, if you really want to tap in, look at the menu. To see how things are long, and it’s too long. Dramatically, I’m about putting bums on seats. For me to separate my idea of commerce from art—I’d be a fool. You can’t do that. I wouldn’t be allowed to do the films I do. So I’m very user friendly as far as the studios are concerned. To a certain extent, I’m a businessman. I’m aware that’s what I have to do. It’s my job. To say, “Screw the audience.” You can’t do that. “Am I communicating?” is the question. Am I communicating? Because if I’m not, I need to address it.
How would you feel about an extended cut. It may not make the crews actions any less stupid, but it may go some way to help answer or at least focus on some of the questions raised by the messy screenplay.
