Darth Maul Minimal Blinking
It doesn’t really need much deliberation to know that Darth Maul’s villainous stare is creepy and a hallmark of his character. Ray Park, the actor who played the role of Darth Maul wore red contact lenses which made it difficult and painful for him to blink. Although painful and uncomfortable, it was decided that it was also a useful and smart character choice.
Due to the discomfort brought by the lenses, he attempted to minimize blinking, which only helped contribute to the character’s creepy presence. Throughout the whole movie, he only blinked three times: when his double-sided lightsaber was cut in half by Obi-Wan when Obi-Wan’s lightsaber pierced through him, and when he registers what just happened to him.
