Director James Cameron has admitted that he himself was surprised by the success of Titanic and in fact had worried about whether it would even turn a profit. "It was a chick flick set in 1912, it was three hours long, and everybody dies in the end -- how could it possibly be successful?" he remarked in an interview with USA Today. "I don't think anybody really believed in its upside potential, myself included." Cameron made his remarks as he began promoting the Titanic "special edition" DVD, which includes the original nine-minute ending that has never been seen. "When we screened the film for ourselves, we didn't like it," Cameron told the newspaper. "It worked on paper and it even worked as a scene, but you watch it as part of the movie and it just doesn't work." Cameron maintained that the "special edition" will be the definitive DVD version -- and that there won't be any future DVD versions. "Our intention here was to jump through all those intermediate iterations and get right to the ultimate version and tell people, point blank, this is it. This is the ultimate disc," he said.
