I began my evening with the sensational British mystery GREEN FOR DANGER with Allister Sim, Trevor Howard, and Leo Genn. I figured out the method for murder, but, alas, I didn't pick the murderer though it was obvious once I got to the denouement.
The Criterion disc was a little iffy at the beginning with some slight flashing and a scratch or two, but then things settled down, and it was the lustrous black and white image - glorious.
