Aspect ratio
I finally found the answer to a question I asked on these boards a while back, and it was right under my nose the whole time.
This movie's main page lists its aspect ratio as 1.37:1. I had noticed that my US-release full-screen DVD contains more visual information than the UK-release anamorphic widescreen DVD -- in other words, the full-screen image isn't a panned-and-scanned version of the widescreen, but the widescreen image appears to be created from the full-screen by cropping at the top and bottom.
Now, I know that many films are shot at aspect ratios of 4:3 and then cropped to make the widescreen version for theatrical release (Cameron does this regularly, for instance), and full-screen DVD releases sometimes use that original footage rather than pan-and-scan. (Cyborg and Terminator 3 are two examples that come to mind -- the latter primarily because the full-screen DVD shows more of Kristanna Loken than the widescreen one does.)
But ordinarily IMDb lists the final theatrical aspect ratios for those films. So I was confused by the fact that IMDb lists this film's aspect ratio as 1.37:1 and I wondered if somehow the full-screen version had been the intended version.
Turns out if you click on more (duhh), you get the full story:
Aspect ratio
1.37 : 1 (negative ratio)
1.85 : 1 (intended ratio)
So the main page is simply displaying the first aspect ratio listed in its database record for the film.
Which means my original suspicion was right: the US full-screen version is a transfer of the original footage, and the UK widescreen version is the one the director intended us to see (and therefore the one I want to see).
I'll probably keep the full-screen version anyway, just in case I ever again watch it on a 4:3 TV; if I'm going to have extra space at the top and bottom of the screen image, I may as well have it filled with additional image information rather than black bars. But I'm glad to know the anamorphic widescreen version is the one Dugai meant us to watch.
