Originally, the character was to be named "Macha Hernandez" and was set to be played by Jenette Goldstein. Yar was originally inspired by the character of Vasquez in Aliens. Goldstein was replaced by Marina Sirtis. At that time, Denise Crosby was set to play Deanna Troi, but she and Sirtis switched roles before production began.
