I've been a Star Trek fan ever since my mom and dad bought me a phaser that fired plastic rings (I easily imagined myself slicing and dicing Klingon warriors and salt vampires), and also a book called Star Trek: The Prisoner of Vega (can still remember that story sentence by sentence yet I haven't read a single page in decades).
For the Love of Spock (2016) is a documentary directed by Adam Nimoy, son of Leonard Nimoy who played the iconic figure for five decades. This treasure trove of information, interviews, and never before released video only deepened my appreciation for the show and the thoughtful, intelligent man who embodied the half-Vulcan character. Like the McQueen bio I mentioned a few days ago, there's much deeper themes here than just another valentine for Trek enthusiasts. Recommended for all.
Here's a link to the trailer.
