I'm drawn to filmmaking that can transport me. Film can immerse you, put you there.

When James Cameron brought me the script, which I developed with both Cameron and Jay Cocks, I wanted to make it a thriller, an action film, but with a conscience, and I found that it had elements of social realism.

One of the elements in the film that really fascinated me was not to look at the world in bi-polar terms of us vs them or east vs west, which was a by-product of the Cold War.

The journey for women, no matter what venue it is - politics, business, film - it's, it's a long journey.

Our film examines the heroism, courage and prowess of the Soviet submarine force in ways never seen before.

What's most galvanizing for me is the opportunity to be topical and relevant and entertaining. That's the holy grail.
