Trivia / Star Trek S3 E7 "Day of the Dove"

• Deleted Scene: In the original ending, Kirk tells Kang that he and his crew will be dropped off on a neutral planet near the Federation-Klingon border. Then, Kirk and Kang debate the issue of the Federation philosophy of peaceful exploration against the Klingons' way of conquest by war, both considering his philosophy to be the better.
• Prop Recycling: The Klingon agonizer used on Chekov is the same one seen in "Mirror, Mirror".
• What Could Have Been:
  • John Colicos was originally going to return as Commander Kor for this episode, but a feature film commitment made this impossible. Had the episode featured Kor, it would've been essentially a reversal of their conflict in "Errand of Mercy". In that episode, the two sides fought of their own accord and were stopped (rather than pushed to fight further) by non-corporeal beings.
  • Jerome Bixby's original story featured the Enterprise receiving a false distress call from a Federation colony, while en route to celebrate "Peace Day" (anniversary of the day the nations of Earth finally made peace with each other). Arriving to the planet, the crew, along with the crew of a Klingon vessel, also lured there with a fake distress signal, are captured by an alien race and forced to compete against each other in bloody duels. The aliens, appearing to be humanoid, turn out to be, in reality, energy beings consisting of "a blob of light", feeding off the aggression of the two enemy crews. Finally, Kirk and the Klingon commander realize they need to work together and make peace with each other, so the aliens won't get violence to feed on. Eventually, the Klingons and the Enterprise crew sing songs and have a peace march together. Good thing they changed this part, it would have made this episode even more painfully dated than "The Way to Eden".
    No more fighting. Forever now,
    The vine and the tree shall increase.
    Let men call each other friend,
    All races joining harmony.
    Build no more weapons. Tend the plough.
    We shall have peace.

    If you have a copy of the Star Trek Songbook you know the tune.
• Working Title: For They Shall Inherit.
• You Look Familiar: The Klingon who says, "Stand and fight, you cowards!" is Pete Kellett, who previously appeared in "Mirror, Mirror" as Farrell, Kirk's henchman.
