Star Trek: The Original Series was the most prominently featured series by far, and the documentary examined Gene Roddenberry's origins and efforts to create the series through the use of re-enactments and archival photographs and footage. New interviews regarding Star Trek were conducted with William Shatner, Leonard Nimoy, Nichelle Nichols, and Martin Landau. The documentary also featured Nichelle Nicols talking about her interactions with Martin Luther King and her (and American television's) first on-screen interracial kiss (with Shatner).
