What I very distinctly remember seeing in the CBS Late Movie presentation of HODS in the 1970s was a boom mike appearing a few times. I didn't see those in the VHS release, which obviously tells me that they definitely cropped the picture all the way around on that one.
On the plus side for both HODS and NODS, each includes German, Italian, and Castilian Spanish audio, but not the Latin American Espanol noted on the package. The German and Castilian narrate the scrolling text at the end, but not the Italian which has forced subs, which will be a revelation to Italian speakers who never were privy to what the end text said before.
I wrote a noveliziation (actually it's novella length) of the original script that's gotten some good feedback.
