1968?!?!?!!!!! I wasn’t even born yet! LOL
I did look it up right after I made my comment. There were some really awful films made in those days. The synopsis I found reminded me why I never watched it. A network must have shown it at some point during my childhood, and one of my brothers liked sci-fi, so that is probably why I have seen a minute or two of it.
The first one was good. The rest of the first round ranged from amusing to back-of-the room trivia. You have not missed much.
You are forgiven. Ha ha.
