When months ago I committed to catching up with The Big Bang Theory (I had seen some episodes of the first few seasons multiple times over the years but never watched the whole thing), I saw an episode in which Sheldon is asked to be a part of a documentary about Spock which was being made by Leonard Nimoy's son, Adam. That's how I learnt about For the Love of Spock and, even though I'm not a Star Trek fanatic, I was immediately interested in it.
As I mentioned above, Adam Nimoy's documentary was supposed to focus entirely on the character of Spock, but, when Leonard Nimoy passed away in 2015 while the film still was in the making, Adam decided to explore the life of his father as well, analysing both his professional and private life, putting under scope his relationship with his father as well.
