Gene Roddenberry tried to explain the differences between
The Motion Picture's Klingons and the original ones by saying that the original show had simply never had the budget and makeup technology to envision the species as it should have been seen, so the apparently new Klingons were just Klingons as they were always intended to have been. (
Cinefantastique, Vol. 37, No. 2, p. 40) He additionally contemplated, "
Just as there are different races of humans, there are different races of Klingons, and the Klingons seen in Star Trek: The Motion Picture
are not the same race as the ones we saw on the original series." Since Fred Phillips expected that the fans would wonder about how the Klingons could possibly have head ridges newly added to their faces, he and Roddenberry came up with the explanation of there being a variety of Klingon races, even before the release of
The Motion Picture. Despite this, the transformation continued to be regarded as a mystery for decades to come. (
