James Cameron has told the London Daily Telegraph that he has spent much of his time since Titanic working on what he calls his "Mars project," which will include a novel, a mini-series and an Imax 3D film. "I've been doing a tremendous amount of research over the past 14 months, going to the NASA centers, meeting and drinking with astronauts, and doing the same in Russia. I need to experience some of the things they go through so that I can write these scripts and the novel as accurately as possible," he told the newspaper. Cameron said that the Mars novel/film and other projects, including his current TV series Dark Angel, have kept him busy. "People assume if you're not releasing a film you haven't done anything. Well, I'm the busiest unemployed film director in Hollywood," he said.
