Director Oliver Stone has admitted he would like to make a second film about the events of 9/11.

World Trade Centre, starring Nicolas Cage, is Stone's first movie about the day, and tells the story of real-life firemen involved in the Twin Towers' collapse five years ago.

However, Stone does not believe one film does the events justice. He said: "It (9/11) was huge. I think it's the basis of another film for me. I've started with the basics, with these men in the centre of things."
