Thanks, colwood. I think I'll stick with my Criterion Laserdisc of CONFIDENTIAL REPORT until Criterion, which obviously has an interest in the property, decides to do something (hopefully) definitive. I made the mistake of ordering that DVD with the commentary by Tony Curtis. Not anywhere as good or complete as the Laserdisc. And of course, though it's always nice to hear from Tony, I could have done as good a commentary myself, and been not much further away from the production than he was.
One day, I suspect, we'll get the real thing.
