When the series was remastered in the fall of 2006, this episode was chosen for the first one for "treatment" and released into syndication. (edit) This episode would be referenced in the Taxi episode "Jim Saves the Network". Jim Ignatowski (played by Christopher Lloyd, who would later go on to play a Klingon Commander in the movie Star Trek III) states that his favorite show was Star Trek. The only episode he didn't like was "the episode with the Romulan Commander. "It wasn't the actor's fault, they just gave him things to say that no Romulan would ever say." (edit) The Enterprise's hunt of the cloaked Romulan ship was inspired by the film The Enemy Below, where a World War II American destroyer hunted a hard-to-detect German U-boat. (edit) First appearance of the Romulans, an enemy race that D.C. Fontana thought were more dynamic villians than the Klingons. (edit) Last episode in which the character of Yeoman Rand appears. (edit)

Kirk: (on shipwide intercom) All hands, prepare to attack. (to McCoy) I hope we won't need your services, Bones.
McCoy: Amen to that. You're taking a big gamble, Jim. (edit) Tomlinson: (to Angela Martine) Happy wedding day - almost.
Angela: You don't get off my hook this easily. I'm gonna marry you, mister, battle or phaser weapons notwithstanding.
Tomlinson: In the meantime I'm still your superior officer, so get with it, mister. (edit) Romulan Commander: A message was dispatched. You've broken the Rule of Silence!
Decius: Only in code, Commander. To inform our Praetor of this glorious mission.
Romulan Commander: Your carelessness might have ended this "glorious mission"! You are reduced two steps in rank! Return to post!
Centurion: (after Decius leaves) Take care, Commander. He has friends, and friends of his kind mean power, and power is often dangerous. (edit) Stiles: Spock...He saved my life after I...
Spock: I saved a trained navigator so that he could return to duty. I am capable of no other feelings in this matter. (edit) Romulan Commander: First study the enemy. Seek weakness. (edit)

Lt. Uhura takes over for Stiles at the navigator's station, but at the end of the episode she opens a hailing frequency from that station, not her normal communications post. (edit) When the Enterprise is hit by the Romulan weapon, the bridge and crew are thrown to the viewer's left. Except two. Kirk (who was standing next to the railing between the command level and Spock's station) should have fallen on the railing, but instead turned and fell toward the navigator. Uhura was at her post and should have been thrown into her console or maybe over closer to Spock. Instead, she got up, ran across the bridge and hit the wall next to the engineering station. (edit) Trivia: Romulan Time (Cycle): A cycle is a time period similar to the Earth hour. We are told that there is no motion on the Romulan sensors for 20 cycles, Kirk
also logs that they were motionless for 9 hours 47 minutes giving a cycle no
more then 29.35 earth minutes. For the Romulan Day see the Star Trek: The Next Generation episode "Unification Part II." (edit) When the Romulans attack Outpost 4 a second time the outpost is sending Enterprise its sensor readings. However the screen switches back to the interior of the outpost, then back to show the ship disappearing even though the outpost is being destroyed at the same time. (edit) In the briefing room while discussing what to do about the Romulan ship there is a book on the table in front of Kirk. Before the long exchange between Spock and Kirk & McCoy the book is turned so the camera sees only the binding. After this exchange the book has moved so that the camera sees the long bottom/top and part of the binding despite no one having made any motions to move it. (edit)
