Star Trek fans are still mourning the loss of actor Leonard Nimoy, and a new trailer has just been released teasing an upcoming documentary about the late actor, who passed away last year.

The documentary was produced by Nimoy’s son, Adam Nimoy, who raised $662,640 in a Kickstarter campaign last spring in order to complete the film, and includes such interviewees as Zachary Quinto (who plays Spock in the reboot Star Trek movies) along with the late actor’s friend and Trek co-star William Shatner.
