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 Kristen is incredibly brave. She played such a good version Bella Swan, people think Kristen Stewart is Bella Swan. She's not, you know? If you meet Kristen, she's wildly kind of giggly and vivacious and rebellious and naughty - all things that Bella Swan isn't.

Once you know the world you know how your character fits into it.

I think it's possible to make a blockbuster that is actually emotional. They don't need to be mutually exclusive.

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'.

I don't love balls and sleeping beauties, that kind of thing. I think the great thing about 'Snow White' is those images have scarred me since I was a child with the Queen, the mirror, the taking of the heart, the huntsman and the enchanted forest.

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