Actually, you'll find the same (although much smaller) light on Magnum's nose just after he puts down his glasses when Higgins enters (7:59 on my player). Slow-motion also shows Selleck's discomfort with the glasses just before!

Have you ever heard the recording of Orson Welles' War of the Worlds original broadcast? The radio annoucement we hear in the '41 section of Lest We Forget is quite similar to the one in the recording. Robin Masters/Welles was there!
