Gene Roddenberry originally conceived the Klingons as looking more alien than they do in the series, but budget restriction prevented this, although a very metallic cast to the skin was added to the make-up design in the third season. When the show moved to the big screen, he was finally able to make Klingons look more alien. The resulting continuity break between TOS and the movies and later series was addressed in "Star Trek: Deep Space Nine"'s "Trials and Tribble-ations," in which the character of Worf confirms that something did happen to make the Klingons appear human, but he says that they "do not discuss it with outsiders." Miles O'Brien asks if it was some kind of genetic engineering while Julian Bashir suggests a viral mutation. In the fourth and final season of the fifth "Star Trek" series "Enterprise" (2001) a two-parter dealt with the exact nature of why some Klingons (that would be the Klingons from the original series) did not have the "knotted" forehead that visually characterized all Klingons portrayed starting with Star Trek: The Motion Picture (1979). The premise was that a group of Klingons on a Klingon-populated world separate from their home world are exposed to a virus that modifies their appearance to that of the way they looked in TOS (and the crew, especially the ship's doctor in "Enterprise" (2001) manage to discover and generate a medical fix for the malady, of course). In short, both O'Brien's and Bashir's inquiries are proved correct.
