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.

Let us not be deceived we are today in the midst of a cold war.

The Cold War is over but Cold War thinking survives.

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.

We're no longer in the Cold War. Eavesdropping on friends is unacceptable.

World War II and the ensuing Cold War compelled the United States to develop a sustained commitment to Western Europe and the Far East.
