Oliver Stone's World Trade Center may have only recently been released in the US but the director says he wants to make another movie about the 9/11 terrorist attacks as the subject matter is too "huge" to cover in one film.
World Trade Center, starring Nicolas Cage as real-life 9/11 hero John McLaughlin, has been acclaimed for its sensitive portrayal of the real-life fire fighters who risked their lives to save those in the rubble of New York's Twin Towers in 2001.
But Stone feels there are more stories to tell and his film is just the beginning.
"It (9/11) was huge. I think it's the basis of another film for me," he said at a BAFTA lecture. "I've started with the basics, with these two men in the centre of things."
