Star Trek III: The Search for Spock follows the same winning formula of the first two Star Trek special-edition DVD releases, although it has no extra footage as The Motion Picture and The Wrath of Khan did. The first disc presents the film with an audio commentary track, the bulk of it handled (appropriately) by director Leonard Nimoy. He doesn't do it in character as Spock, but rather chortles and gushes about his cast and crew, especially William Shatner. Other contributors include Robin Curtis, who explains how Nimoy and writer Harve Bennett made it easy for her to take over Kirstie Alley's role as Saavik.
