Writer/director James Cameron has expanded his vision for the future of Avatar from three sequels to four, according to The Hollywood Reporter. Cameron was a surprise guest at 20th Century Fox's CinemaCon panel, announcing that the sequels would be released annually beginning with the second Avatar on December 28.
"We have decided to embark on a truly massive cinematic process," Cameron said, explaining he decided to expand the Avatar franchise to five movies because "we began to bump up against the limitations for our art form" with only three sequels.
Cameron is reportedly working with "a team of four top screenwriters" for the sequels, with each being standalone that "will together create a saga."
"So far, the art I'm seeing, is in pure imagination, really far beyond the first film," he said. "It's going to be a true epic saga."
