This is one of numerous episodes of SGA (along with SG1 & SGU) which have "replicants" of another member of the show. The idea was spawned in the "Golden Age" of science fiction writers (1938 to 1946). "Do Androids Dream of Electric Sheep" (1968) is a novel penned by Philip K. Dick. He was one the greatest sci-fi writer's in history. In fact, only Stephen King has had more stories and novels made into films (or TV shows). "PKD" (as his fans know him) has had over a dozen outstanding films made from his body of work. This story is the foundation for "Blade Runner" (1982); a stunning film directed by Ridley Scott. A sequel is "Blade Runner 2049" (2017). It was directed by Denis Villeneuve, one of the very best directors alive today. Ridley Scott was Assistant Director. Also, screenwriter Hampton Fancher wrote most of both film's screenplays. A few of the other films based on his work follow: "Total Recall" (1990 and again in 2012); "Minority Report" (2002); "The Adjustment Bureau" (2011); "Next" (2007) and many more. Back to this episode of SGA, it owes much to PKD. Enjoy this show, but please read his work; it is brilliant.
