As yesterday was the 45th anniversary of the first airing of "Spock's Brain," I decided to watch the the episode last night. I had recently seen the episode on MeTV, but I was dismayed at the editing of the show to make it fit today's time slot. Watching the original version in its entirety for the first time in quite a while was interesting. Just an observation after watching the show. I realize the official story why this episode was chosen to open the third season was that it was the only episode in the can ready to go, but I also wonder if it was chosen because it featured all the members of the cast. The scene on the bridge where Kirk is conferring with Sulu, Chekov and Uhura as to where Spock's brain may have been taken really gave the show a more ensemble feel, although it ended up featuring a Chekov and Kirk exchange with the other two looking on. I had forgotten that later in the episode, as the show came back from commercial, the captain's log was given by George Takei with a shot of Sulu in the command chair. I wonder if it was the intent of the creators to give the show more of an ensemble feel similar to what had been the situation in the early episodes of the series. When I think about it, the secondary characters were given their moments from time to time in the third season more that they had been given previously.
