Was Titanic Super 35? I forgot he was into that. In a weird way, it helped keep his movies very visceral because of the grain. I think it was Xhonzi that said in the Last Movie thread he was glad that Cameron kept T2 rough around the edges to match the first film. I disagree with that, I think T2 is way too slick to even compare to T1, but it's that grainy, fuzzy quality that I think Xhonzi was catching onto, had T2 been filmed anamorphic it would have looked amazing but also would have highlighted the differences even more. That's one reason I regret the Aliens blu-ray, 1986 was a bad year for film stocks, especially on 35mm, but that grainy super35 quality is what I really loved about Terminator and Aliens, it gave them a certain documentary-like, grindhouse feel that matched the quick cutting and handheld camerawork.
I never felt that way about Titanic, but I guess by 1996 technology was just cleaner in general.
