The remastering of those gems is a project on which the filmmaker and producer Jon Landau have been working for four years.
"Looking back and seeing we hadn't done 4K transfers of all these and, of course, the fans have been banging on about this for ages. it was like, 'When are we going to get around to this?'" Cameron recalled. "I think what people don't appreciate is that it is basically a week of my time to do a proper transfer, updating it every day as they go off and do color and power windows and all that sort of thing."
"We recompose, shot by shot, going through the film, and I'm pretty serious about this. I don't just let somebody else go through it because I have such a vivid memory of what the color was and what we fought for on the set and in post, maybe all the way back to when the color was done with photochemical film, which is when I rode my Stegosaurus to the studio. These restorations have been on top of our day job, which is called Avatar. Those movies are quite good."
The pair, who have been collaborating for 30 years, consider the 4K versions to be the definitive versions of the classic titles.
"It was important to get it just right because, theoretically, we shouldn't have to do it again," Cameron mused. "4K is sufficiently above the innate resolution of the photochemistry of that period. Are we going to do 8K? 12K? You're going to see the grain more clearly. I think this is it, so we wanted to do it and do it right, and that's taken some time."
