When contacted by his talent agent, Wright jumped at the opportunity to create a character wholly unique to the "Star Trek" franchise. When he auditioned for the role of Tuvix, Wright had never seen "Star Trek: Voyager" and was completely unfamiliar with the characterizations of Tuvok and Neelix. Instead, he drew upon his prior experiences with the characters' actors, Tim Russ and Ethan Phillips respectively, to successfully vie for the role. Executive producer Jeri Taylor was pleased with the casting of Wright, marveling at his ability to bring credibility to the prospect of two characters in one.
