Ronald D. Moore, the producer of Carnivale and writer for Star Trek: The Next Generation and Star Trek: Deep Space Nine, boldly re-imagined the original 1978 space opera of humans versus the robotic Cylons. He teamed up with co-executive producer David Eick on a powerful and dramatic update of the Galactica story. Gone are the technobabble, disco outfits and Egyptian helmets of the original series. The modern show introduces new elements to the Galactica story. The Cylons have developed human-form models that are indistinguishable from real humans. The Cylons have a monotheistic religion in contrast to the polytheistic religion of the human Colonies.
