Trek series since the end of The Original Series. In the Star Trek: The Next Generation episode "Relics", only the engineering console was reconstructed, with the Captain's chair and the navigation consoles rented from a fan and the remaining consoles were edited in digitally using blue screens. Incomplete sets were also recreated for the Deep Space Nine episode "Trials and Tribble-ations", but these involved digitally inserting the actors into previous footage of The Original Series and so a full bridge set was not recreated. Further sets for the Defiant were created for the second part of the episode, which included designs previously used in "Trials and Tribble-ations" for the Jefferies tube. The other sets included the Rec Room, Captain's quarters and the briefing room. Classic Original Series style uniforms were worn by some the main cast in the second installment; however, the production crew mistakenly gave the USS Defiant a unique uniform insignia different from the iconic delta (arrowhead) badge. This mistake likely stemmed from the erroneous fan theory that every starship in TOS had its own unique insignia. In the TOS episode "The Tholian Web" we clearly see the dead crew of the Defiant wearing the delta badge. Bakula wore the wrap-around green uniform previously worn by Shatner in several episodes including "The Trouble with Tribbles", while Trinneer, Keating and Montgomery donned red shirts. Bakula joked: "Did we run out of material for Jolene's skirt?" as Blalock wore the science-blue miniskirt in the style of that worn by Christine Chapel. The normal Enterprise costumes also underwent changes, with those worn by female members of the crew having a portion removed to reveal their midriffs. Original Series props such as phasers and PADDs were also created for the episode. Despite the mirror-Enterprise being destroyed in the first installment, during the second episode the standing sets were reused to represent the ISS Avenger. Both a Tholian and a Gorn were created in post production using CGI. The Gorn in particular required an actor in a tracking suit to allow the actors to interact with the character and give the animators something to overlay the CGI on. Stunt coordinator Vince Deadrick, Jr. wore the suit for scenes that required movement, while David Anderson wore it for static shots. Sussman also wrote biographies for Archer and Hoshi that would briefly appear on screen. Included in these were references to Archer becoming President of
