A quick word about grain reduction. I really don't have a problem with what I'm seeing here, as it seems to consistently represent what a second generation element would look like from the era. There is certainly noting scrubbed, as I've read in some other threads on other sites.
Considering that most theatres never got prints as close as "second generation", if this Blu-ray looks that good, I don't think anyone has anything to complain about.
I've had a 16mm print of "To Kill A Mockingbird" since about 1964 (I only hope it hasn't gone vinegar). It's a very sharp print with below average grain for a 16mm B&W print. From the description of this Blu-ray, I'm sure it will look better then my 16mm print and probably as good on my digital projector, as a 35mm release print looked in the theatre when it originally came out.
I have the first DVD that they released of "Mockingbird"(1998), which was pretty soft and blurry. The second DVD release (2005), an anamorphic 1.85:1 DVD, was only slightly better. However, for some strange reason they felt it necessary to electronically "zoom out" on the titles, leaving black lines on the sides, which disappear and return to full width after the titles. Since the titles were safe and in no danger of being cropped, I can't understand why they've done this. This miserable practice has also been done by Disney on their animated classics, which also would have had safe titles without it. Since I haven't seen this Blu-ray yet, I hope they haven't done the same thing again.
