Pilot (Supernatural) [SEP] Introduction
"Pilot" is the first episode of the television series "Supernatural". It premiered on The WB on September 13, 2005, and was written by series creator Eric Kripke and directed by David Nutter. The "Supernatural" pilot introduced the characters of Sam (Jared Padalecki) and Dean Winchester (Jensen Ackles), brothers who travel throughout the country hunting supernatural creatures, as they battled a ghostly Woman in White (Sarah Shahi) while searching for their missing father (Jeffrey Dean Morgan). Kripke was developing the concept for ten years before it was greenlit as a television series. Before it could be filmed, the script underwent numerous revisions.
