Wait, I thought all the Heisei Godzilla films were 1.85:1 to begin with? IMDb says it's 1.85:1, and I was always under the impression that it was that AR. Which would mean this is NOT cropped other than the slight modification to 1.78:1 (which IMO doesn't count - if it's cropped rather than vertically opened, the picture lost is usually in line with framing variations that would have occurred from theater to theater in the film's original run)
It wasn't until the Millennium era that they went back to 2.35:1.
And it was the Showa films that were cropped to 1.78:1 on MonstersHD.
