Adam Nimoy will play himself in the 5 November (15) episode of the show, which is titled The Spock Resonance.

His dad, who lost his battle with chronic obstructive pulmonary disease on 27 February (15), never appeared on The Big Bang Theory, but he did provide the voice for a Mr. Spock action figure in one of Dr. Sheldon Cooper's dream sequences.

In the new Nimoy episode, Adam invites Cooper, played by Jim Parsons, to participate in a documentary about his late father.

Leonard Nimoy portrayed Mr. Spock in Star Trek TV series and films.
