This "Special Edition" Pioneer LaserDisc was released in 1993, featuring a 15-minute extended version of the film that restored deleted scenes, interviews with cast and crew, storyboards, designs, and unrestored deleted scenes. Cameron stated he did not use the label "Director's Cut" because he considered the theatrical releases to be definitive and the extended versions as opportunities to restore "depth and character made omissible by theatrical running time”.
