A “vanity card” often appears after each episode and “Theory” creator Chuck Lorre shares his thoughts on a certain subject using this medium.
On the March 5 episode, the vanity card had a picture of Nimoy and read, “The impact you had on our show and our lives is everlasting,” according to the Hollywood Reporter.
Nimoy – or at least his voice – guest-starred on an episode in 2012 when Nimoy provided the voice for an action figure of his “Star Trek” character Spock.
Many of the main characters on “Theory” love anything to do with science fiction or fantasy and the show “Star Trek” has been brought up many times.
Nimoy spoke with Collider in 2012 about how he got involved with “Theory” and why the appearance was ultimately in voice form.
“They are a wonderfully talented bunch of people and it is a smart show that is full of talent,” the actor said of the sitcom. “They asked me to appear on the show. For various reasons, a physical appearance didn’t work out, but when they came up with this idea of voicing the Spock character with Sheldon being given a ‘Star Trek’ transporter, I thought the whole idea was wonderful. It was a way for me to deliver an appearance on the show and to work with that very, very talented bunch of people.”
Nimoy died on Feb. 27. Following his death, various co-stars offered their remembrances. “I loved him like a brother,” William Shatner, who portrayed “Star Trek” captain James T. Kirk, said. “We will all miss his humor, his talent and his capacity to love.” Meanwhile, “Star Trek” co-star Nichelle Nichols said of Nimoy, “He was a true force of strength and his character was that of a champion. Leonard's integrity and passion as an actor and devotion to his craft helped transport 'Star Trek' into television history. His vision and heart are bigger than the universe.”
Actor Zachary Quinto, who took on the role of Spock for the new “Star Trek” films, said of Nimoy’s death, “My heart is broken. I love you profoundly my dear friend. And I will miss you everyday. May flights of angels sing thee to thy rest.”
