Surely Mr. Harris can elaborate on this more authoritatively than I can, but it's my understanding that the three-strip negatives for both Singin' in the Rain and An American in Paris were lost in that nitrate fire many years ago. Or at least most of the negatives. On the Town, too.
Given that, the current DVDs look pretty good, especially Singin'. An American in Paris is a little more variable.
I wonder if the new SEs will be LVI projects.
Not having seen their techniques applied to three-strip Technicolor, I'd be interested to see what they can do with what seems to be less than ideal source material.
I do hope they'll give their transfers a little more "zip," contrast-wise than, say, Now, Voyager or The Bad and the Beautiful, which are clean but a bit flat.
