The director sits down with TotalFilm to talk about his “Aliens” prequel and the challenges of filming in 3D.

Here’s a snippet:

“Q: Is it more immersive, giving depth?

So you can literally, as it were, twiddle a knob, and the depth will increase. It’s kind of bizarre, but there it is. Technologically it’s absolutely staggering.
