Oh, wow! My favorite zombie flick (along with the original). You guys have made my day! Cannot wait for this!
I did some googling about the Twilight Time color issues, and I found this article pretty interesting. It says Sony reportedly made the transfer "with the approval of the film’s cinematographer, Frank Prinzi." It also says Savini calls it "fantastic."
*shrug* Wouldn't be the first time I have disagreed with a director over changes to a theatrical release. ;) All I know is that I am stoked for this preservation!
Cheers,
