Hi, Paul. Welcome to HTF.
I'm also very excited about this upcoming DVD, but haven't heard anything yet in terms of quality.
(FYI, singling out Robert Harris in your thread title is kind of frowned upon. I made a simliar faux pas when I first joined up. If he has something to add, he usually stops by anyway.)
I saw SUNSET BOULEVARD on the big screen recently, and the print was struck from the same source as the upcoming DVD(at least according to the person who introduced the presentation). That print was gorgeous so I'm expecting a nice DVD. I look forward to retiring my old faded laserdisc.
