This is more of a question then a review.
When was this episode filmed? Reason being is that I was wondering if this was the last production Theo Marcuse was in before his untimely death.
Everything I found on him states he died a little over a month from when his Star Trek episode AIRED not filmed;). So it's been said he never saw this 2nd appearence on the www because he died in Nov of 1967.
This one aired in Jan of 1968
So...was this the last thing he did before his death?
He was such a great believable villian.
So much so that I truly believe he would have landed a role in a future James Bond film had he not died so early in life.
