For their appearances on Star Trek: The Next Generation, makeup artist
Michael Westmoregave the Romulans V-shaped forehead ridges to "compete" with the Klingon redesign introduced in
Star Trek: The Motion Picture. (
The Art of Star Trek, p. 92) The Romulan ridges also developed from efforts to make them look more menacing than how they had appeared before and physically differentiate them from Vulcans. "From the very first moment they appeared on-screen," Westmore commented, "the viewer had to take them seriously, rather than seeing them as stereotyped villains with pointed ears [....] I devised a forehead that had a dip in the center, and then I hollowed out the temple area. We wanted to stay close to their natural forehead, not making them look Neanderthal, but giving them a built-in sullen expression they couldn't get away from." (
