Re-Used Planet Sets
by Jörg Hillebrand and Bernd Schneider
Many sets used in Star Trek were later modified or even recycled without changes to represent a different environment. Here are quite a few examples. Please note that every statement made here is based on observation, we can only speculate why and how exactly modifications were done. Finally, everything should be taken with a grain of salt. Certainly we are not supposed to watch closely enough to see that two planets are the same.
The backdrop representing Talos IV in "The Cage" also appears as Talos IV in TOS: "Where No Man Has Gone Before".
All re-used matte paintings of TOS and their modifications for TOS-R are shown in the extensive article on Planet Surfaces in TOS and TOS Remastered.
Buildings from "Logan's Run"
The Sandmen Headquarters from the science fiction movie "Logan's Run" (1976) appears on two occasions in Star Trek, in TNG: "Final Mission" and "Tapestry". Mike Okuda tells us: "That wasn't a miniature building, but rather a large painted backdrop. I love Logan's Run, so I tried to push the use of those backings from that film whenever it seemed appropriate, although the actual choices were made by the production designers.... In Logan's Run, that painted backdrop would have been based on their (very large) miniature city, and that particular building in the miniature was based on a real building in Texas that was used for location filming in the movie. (I think it was Sandman headquarters.)"
Mike Okuda pointed us to another re-use of the "Logan's Run" city in Star Trek. A portion of the cityscape with is characteristic pyramids appears on the Enterprise's viewscreen, behind Admiral Bennett, in "Star Trek V".
The re-uses of the matte painting that first appeared in TNG: "Angel One" are covered in the separate article Re-Uses of the Angel One Matte Painting.
The matte painting was first seen in TNG: "Unnatural Selection". A couple of modifications were made when the picture was supposed to represent the Arkaria Base in TNG: "Starship Mine". The sky is somewhat different here but has the same cloud patterns. The building is identical. The only obvious alteration is that the shuttle in which Dr. Pulaski arrived on the planet was removed. The rest can be attributed to just a different hue on film.
The matte painting underwent some more extensive alterations for Ohniaka III in TNG: "Descent". A new building was added on the left side of the crevice, the mountains were altered, the main building got a second dome, some gaps in its structure were filled and an antenna was taken away.
Tau Cygna V
The matte painting of the human colony on Tau Cygna V in TNG: "The Ensigns of Command" returned in DS9: "The Maquis", here as the Maquis colony on Volon II. No differences are visible on the actual painting. Even the aqueduct that used to play an important part in the TNG episode was retained. But while there were no celestial bodies on Tau Cygna V, a moon and later on a sunrise or sunset was inserted on Volon II.
Delta Rana IV
The matte painting of the devastated planet from TNG: "The Survivors" was modified and reappeared as Melona IV in TNG: "Silicon Avatar".
The scenery of the devastated planet Turkana IV (TNG: "Legacy") was modified to depict the planet T'Lani III in DS9: "Armageddon Game". The color of the sky was changed, a wall was inserted into the foreground, and finally a new smaller building was added in the center of the picture. This is the one where O'Brien and Bashir seek shelter.
It is worth mentioning that T'Lani III with all of the above mentioned modifications to the original look could be seen very briefly in one of the visions of the linked Cooperative in VOY: "Unity".
Stock footage of the isolated Earth colony on Moab V (TNG: "The Masterpiece Society") was used for the surface of Torman V in TNG: "Chain of Command".
The Carraya prisoner camp set is composed of the model of a building complex that is inserted into a jungle landscape. The model can be seen from two different angles: a side view and an aerial view. The first one was filmed as a day version, a dusk/dawn version and a night version.
The side views were recycled for DS9: "The Storyteller" to act as a Bajoran village. The day and dusk/dawn takes were taken over without alterations. Only the sky is somewhat more reddish on the latter than on Carraya.
The aerial view of Carraya was modified more extensively and became the settlement on the planet Meridian. A large hall was added to the model, and this matches with the full-scale set of Meridian. Carraya, as a prison, was naturally surrounded by walls. In order to make Meridian look more pleasant, a small building was put outside the walls and the watch towers were modified too.
The matte painting of Ronara in TNG: "Preemptive Strike" shows the Maquis colony in the daytime and in the dusk or dawn. Both versions were re-used for Yadera II in DS9: "Shadowplay". The daylight picture was almost unnoticeably modified, the mountain range in the background is now different. The same change was made to the night version. In addition the sky was darkened and more lights in the windows were inserted.
A view of the Ocampa underground city reappears on a screen as Argala habitat on the Nyrian ship in VOY: "Displaced".
The exotic landscape of Risa from DS9: "Let He Who Is Without Sin" reappeared one year later in VOY: "Random Thoughts" as a view of the Mari homeworld. It becomes obvious at the first glance that the central building with its characteristic chamfered tubes, the shore with the palm trees and the bridge on the left were taken from the Risa scenery. The building with the columns in the foreground on the right is the Delmar T. Oviatt Library of California State University, Northridge.
The rest of the structures on the Mari homeworld is not new either but wastaken from various other episodes, including Ronara from TNG: "Preemptive Strike" (see above), the Chronowerx building from VOY: "Future's End, Part II" and Starfleet Headquarters in San Francisco from DS9: "Homefront". The building with the round tower from the latter episode can be seen at a different angle on the Mari homeworld. It is obviously a model. Some of the smaller structures on the left may have been taken from Ligon II (TNG: "Code of Honor") or Kataan (TNG: "The Inner Light"). It seems that the Mari are not satisfied re-using various small items, they have a collection of entire buildings from the Alpha Quadrant on their planet!
The Zahl colony, one of Annorax's targets in VOY: "Year of Hell", could be seen once again as the Qomar homeworld in VOY: "Virtuoso".
The planet from VOY: "Blink of an Eye" is out of sync with the rest of the universe, which gave the Art Department the unique opportunity to show how the same location on that planet evolved throughout the centuries. But even in this exceptionally beautiful sequence of shots there are at least two re-used elements: The building on the right in the modern cityscape of the planet originally appeared on the outpost in VOY: "Darkling". The dome with the triangular segments on the left is taken from Risa.
A CGI model with characteristic cone-shaped buildings could be seen as the Torothan homeworld in ENT: "Desert Crossing". It reappeared without open fire and with new small windows, insinuating a larger size, as the Klingon Qu'Vat colony in ENT: "Affliction".
The same digital translight represents Keto-Enol in ENT: "Canamar" and Andor in ENT: "Proving Ground".
In TOS: "Bread and Circuses" stock footage of Roman looking buildings was shown to represent the planet of 892-IV, among them the Great Dome of the Massachusetts Institute of Technology in Cambridge and the California Palace of the Legion of Honor, an art museum in San Francisco.
Toronto City Hall
The then modernistic city hall of Toronto (opened in 1965) is one of the places showing up in the Iconian gate in TNG: "Contagion". It may be supposed to represent an alien planet here, rather than Earth which was no place of interest at the time of the Iconians (at least none that we know of).
Tillman Water Reclamation Plant
One of the most prominent and most frequently used real locations of Star Trek is the building and the Japanese Garden of the Donald C. Tillman Water Reclamation Plant in the San Fernando Valley. It was used for the first time to film the Edo Planet in TNG: "Justice".
With different upper stories the Tillman Plant appeared as two distinct buildings of Starfleet, namely of the Academy in TNG: "The First Duty" and as the supposed Headquarters in DS9: "Homefront". In DS9: "Paradise Lost" the building could be seen up close and without upper stories, so this must be yet another Starfleet building of the same style.
Finally the Tillman Plant was used for the devastated nameless planet in VOY: "Time and Again".
Aside from these appearances of the building, the Japanese garden of the installation could be seen on even more occasions, just like in TNG: "Ménage ā Troi" as Betazed and in DS9: "Meridian" as the planet of the same name (see also above in the category of models and paintings). Looking at the photo of the real building, we can see the stone garden as it appeared in VOY: "Homefront" and also in VOY: "In the Flesh", although the building was modified for the latter episode.
The Brandeis-Bardin Institute is a Jewish retreat located in Simi Valley, California. A matte painting of the futuristic building (apparently with some liberties) can be seen in "Star Trek: The Undiscovered Country" as the Khitomer conference hall. It appears as a real location and as a matte painting (again with some modifications compared to the real building) as Lore's headquarters in TNG: "Descent, Part II".
El Mirage Dry Lake
The El Mirage Dry Lake Bed in the Mojave Desert appeared as the moon Lambda Paz in TNG: "Final Mission". The location was filmed from the same angle for VOY: "Caretaker". The mountain range in both episodes is clearly the same.
The footage of Patrick Stewart as Captain Picard on Kataan in TNG: "The Inner Light" was filmed at Bronson Canyon, the village was added in post production. VOY: "The 37's" was also filmed at Bronson Canyon and features a very similar shot.
Some junk was arranged in Bronson Canyon to build the Bajoran refugee camp on Valo II for TNG: "Ensign Ro". We can see a screen image of this very camp in VOY: "Displaced", this time supposed to depict the Tanatuva habitat on the Nyrian ship.
