It was recently reported that costume designer Robert Fletcher, who worked on the first four Star Trekfeature films, and designed many iconic costumes of the franchise, has passed away peacefully in his home in Kansas City, Missouri, on 5 April, at the age of 98. 
Guy Vardaman is a stand-in performer who often appeared in the role of Darien Wallace on Star Trek: The Next Generation. He also served as photo double for Data during the majority of the show's run, from the first season's "The Big Goodbye" through the final episode, as well as for Star Trek Generations. Additionally, he was a Research Consultant for the show's creator, Gene Roddenberry.
Hailing from Glendale, California, Vardaman spent a good part of his life in San Jose. He grew up watching Star Trek: The Original Series, becoming a huge fan of the series. He never dreamed that he would become a part of the Star Trek universe himself.
To support himself while he was in school, Vardaman joined the Screen Extras Guild to acquire a part-time job. Less than two weeks later, while signing up with casting, he was spotted and approached for a job on Star Trek: The Next Generation. As it turns out, the man originally approached for the job was unavailable, prompting the need for a replacement. Despite some initial reluctance from the wardrobe department, Vardaman was fitted with an operations yellow Starfleet uniform and reported for work the following day.
