The NBC cult-hit series "Dark Skies" mixed fact and fiction in a story of the UFO cover-up in the 1960s. It was created by Bryce Zabel and Brent V. Friedman who discuss the controversy and paranoia behind-the-scenes of the series that began its run with a two-hour film based on the idea that John Kennedy was killed because he wanted to disclose the truth about UFOs in his second term.
