so I really treasured the experience." Part of Manny Coto's plans for season five of Enterprise would have included a return to the mirror universe crew first seen in "In a Mirror, Darkly". It would have been across four or five installments, which Coto described as a "mini-series within a series". Visual effects and costuming The opening sequence featured the reuse of footage from Star Trek: First Contact, where Zefram Cochrane makes first contact with the Vulcans, for which both James Cromwell and Cully Fredricksen agreed to accept Screen Actors Guild minimum salaries. Herman Zimmerman had kept the lower portion of the Vulcan vessel from that scene, and made it available to use for reshoots. While Enterprise was normally shot in digital, the mirror-First Contact scenes were shot on film so that they would match the appearance of the original footage. An alternative opening credits sequence was created, which Sussman credited Coto for. It featured footage used in other Paramount Pictures productions, including the Soviet nuclear submarine Konovalov firing a torpedo from The Hunt for Red October. Other elements include an atomic explosion, battleships, tanks and fighter jets. Zimmerman led the construction of a full three-quarters around set to represent the bridge of the USS Defiant, which was used from the final day of filming the first part of this episode. It was the first time that a bridge set of that scale from a Constitution-class starship from The Original Series had been used since the final episode "Turnabout Intruder" was aired in 1969. Senior illustrator Doug Drexler was involved in the design; he had previously worked on the research that went into re-creating parts of The Original Series era USS Enterprise for the Star Trek: Deep Space Nine episode "Trials and Tribble-ations", as well as a set which was exhibited in Hyde Park in London. Other designers included in the creation of the set were Anna Packard, Michael Okuda and James Van Over. The actual construction of the set was in the hands of Tom Arp and his team. Sussman said of the set, "I think the bridge set is remarkable. I hope fans will be thrilled to see that set again in all of its glory. I feel that it probably looks better than the original in many respects, if you compare them side by side." The bridge of the Enterprise had previously been recreated twice in Star
