10 Dumb Mistakes Star Trek Wants You To Forget
6. Klingon K't'inga-class Ship In Enterprise
Matt Jefferies designed the original Klingon battlecruiser for The Original Series, which cut an imposing figure once introduced in Errand of Mercy. When it came time to bring this ship to the big screen, it was given a detail-centric overhaul, as the original model was far too smooth for the close-up shots required for The Motion Picture.
The ship was a new design by the time the Enterprise 1701 encountered in around Organia, so when a K't'inga-class battlecruiser was encountered by the NX-01 in the first season episode Unexpected, this created a fairly annoying continuity error.
Ron Bunchune and Koji Kuramora of Foundation Imaging had built, free of charge, a new D-4-class battlecruiser for the scene in question, yet it was decided that their CGI model didn't have enough windows on it. The producers asked them to redo it, to which they bluntly said no, feeling this was highly ungrateful. Instead, the K't'inga model was used, as it was readily available, having been built for Star Trek: Deep Space Nine.
The appearance of this ship remains a low mark in Enterprise's first season, which was already struggling to find its feet.
