Star Trek: 10 Things You Didn't Know About General Chang

10. Smooth Criminal

Chang's design was a mix of the classic Klingons from the Original Series and the updated design from the movies. While he had a very subtle set of ridges on his forehead, he didn't have to don the long-haired wig that almost every other Klingon had to have. This came down entirely to Plummer.

Despite several phone calls with Leonard Nimoy, when approached by production to appear as Chang he initially turned them down. Director Nicholas Meyer, for his part, refused point-blank to consider anyone else for the role of Chang, as he had written it with Plummer in mind.

The heavy prosthetic make-up was the main sticking point. From the production's point of view, having pronounced ridges and long hair was simply par for the course when depicting a Klingon, but Plummer worried that this would affect the overall performance.

Thus the design of the character was toned down. He was bald, rather than long-haired and, although his skull was a normal shape, his ridges were much smaller than those that had been added to Klingons in previous movies.
