Laughing Vulcans. Row, row, row your boat. Triple-boobed cat aliens. Rocket boots. "What does God need with a starship?" Of all 13 Trek movies, this one is primed for HDTGM.
Synopsis: A renegade Vulcan makes Kirk (William Shatner), Spock (Leonard Nimoy), McCoy (DeForest Kelley) and the Enterprise go to a planet at the center of the galaxy.
The behind the scenes stuff is fascinating. Shatner's ego couldn't take the fact that Nimoy directed the previous two films so he demanded to direct their final film in the series. The film got caught up in the writer's strike and Shatner ran through the budget, leading to terrible reviews and box office, so much so the cast decided to come back for The Undiscovered Country so they could finish on a high note.
