I think what we're trying to do as filmmakers is make a big, gritty, raw, epic movie and within that show things graphically in a way that they haven't been seen in that world before.

I think you can get away with being a bit more political in science fiction.

To me, casting is all about finding a character within the actor off the screen as much as on the screen.

In a way I think why the Ghost story is very relatable to a large audience is that it's kind of a coming of age story and it's a realisation of 'I am what I am - what has happened to me, good or bad, that is the sum of who I am now'.

To trust so much in our devices and sync everyone's device up - we tell people where we are, what we buy and where we shop, who we talk to - and that goes somewhere. The ghost of information technology out there, and one of the points... of the manga and anime was trusting in technology.

You've got pressure making any film, frankly. Whenever you're doing something in the public eye you have to silence it really, you can't read the blogs and take them at face value, you just have to say, 'I'm lucky enough to be in this position, to do this job'.

Trying to ground everything in reality was the most important thing to me.
