The exterior shots of the shuttle that Picard, Worf, and Crusher show that they are in a Type-7 shuttle. However, the interior shot is consistent with the smaller Type-6 shuttlecraft.
During the scenes on the Enterprise, Admiral Nechayev isn't wearing a communicator badge.
This is the first episode that Deanna Troi starts to wear a standard Starfleet uniform, as requested by Capt. Jellico.
If Celtris III was an uninhabited Cardassian planet (as asserted by many, including Picard), why would Solok make cargo runs there (as also asserted by Picard)?
Gul Lemec: What is going on? I have been waiting here for over an hour!
Jellico: I'm Captain Jellico. I believe you know Commander Riker and this is Lieutenant Commander Troi. Let's get to it, shall we?
Gul Lemec: This treatment is a deliberate insult to the Cardassion Union. I have been kept waiting here for over an hour!
Jellico: Then I'm sure you're ready to talk.
Cardassian Interrogator: You should prove an interesting challenge, possibly the most interesting to come through that door in many years ... in this room, you do not ask questions, I ask them, you answer and if I am not satisfied with your answers, you will die.
The look of the Cardassian uniforms has been given a redesign since their last appearance in season five's "Ensign Ro."
Stock footage of Moab IV matte painting from "The Masterpiece Society" is recycled for the surface and habitable structure of Torman V here.
Shot of Enterprise side-by-side with the Excelsior-class ship recycled from "Best Of Both Worlds."
The part of Solok was originally supposed to be Quark (and thus played by Armin Shimerman), thus being a crossover with Star Trek: Deep Space Nine.
David Warner also played St. John Talbot in Star Trek V: The Final Frontier, & Chancellor Gorkon in Star Trek VI: The Undiscovered Country.
This episode was originally intended to be the first crossover episode with Deep Space Nine. Rick Berman and Michael Piller thought it was too early to do a crossover episode and the idea was put on hold until later that year.
