Remarkable were the segments that showed the model makers at Magicam working on the various studio models at their company, the fitting of prosthetics to create various alien makeup, and the shaving of Persis Khambatta's head for her role as Ilia. Particularly noteworthy was the footage of the construction and destruction of D7-class breakaway models which was shot in the last quarter of 1977, while Magicam was still entrusted with providing all the visual effects for The Motion Picture's immediate predecessor, Star Trek: Phase II.
