In a documentary, For the Love of Spock, Adam Nimoy claims that his father would have been happy to play Spock "indefinitely." Certainly a career defining role, Nimoy never wanted to retire from his iconic Vulcan character. 

Despite passing away in February of 2015, Leonard Nimoy's legacy lives on. His son stated, "He was in the original pilot episode of Star Trek and the only cast member to continue on into the new J.J. Abrams incarnation." He told Digital Spy, "That was a great source of pride for my father. It gave him a real sense of meaning to his life and a real book-end, real closure to his professional career."  

Contrary to popular belief, Adam insisted that his father never felt typecast in the role, nor did he resent the character of Spock. Adam says, "He loved playing Spock. What threw the fans off was, in the mid '70s, he published an autobiography entitled I Am Not Spock…"

"With the title of the book, he was simply trying to clarify that he was often confused with the charcter — when he's an actor from Boston, not a Vulcan from Vulcan!"

For the Love of Spock is more than a retrospective of Leonard Nimoy's career. It highlights Spock's impact on society, pays tribute to the late actor, and explores the father-son connection between Adam and Leonard. "He was a man of great nobility and did not want this to be a puff piece for 'the incredible career of Leonard Nimoy.'"
