"nable to reuse the Borg cube built for the television series, created out of inexpensive pieces from model kits, a new cube had to be designed. Described by Eaves as "nonsensical", a distinctly new surface was designed, distinguished by interlocking shapes and angles, with a hidden hatchway for Eaves' Borg sphere. Intricate details of ILM's Borg cube model were achieved through the use of recycled paper clips.
As described by visual effects supervisor John Knoll
, time allotted for post production visual effects and model building resulted in a "brutal effort". Not only did ILM's team have to construct the Enterprise
-E, large models representing the Borg sphere, the new Borg cube, and the Phoenix
were also required.
Even more so than the previous film, the First Contact
visual effects team also utilized computer-generated imagery, lending itself to sequences that required large numbers of starships. To stand up to the Borg cube alongside the new Enterprise
and the old Defiant
, ILM art director Alex Jaeger
designed sixteen new Starfleet vessels, four of them rendered digitally and appearing in the massive opening battle sequence. The new starships included Akira-class
, and Norway-class
vessels; the latter starship was lost after production due to a computer glitch, never to appear in Star Trek
again. Also included in the melee were a Nebula-class
starship, a Miranda-class
vessel, and an Oberth-class
science ship in its final use. As a joke, the Millennium Falcon
CG model (created for the Star Wars
Special Editions) was inserted into the Borg attack, though generally indistinguishable.
