“By the end of the first season most of the questions in the pilot will be answered,” says e.p. David Goyer. The exception: The “overarching cause of why the blackout happened” won’t be revealed until the end of the series.
David Goyer is an “enormous fan of Lost” and says the show “proved to me that there could be a place on network television for” dramas with large ensembles featuring different shades of morality. Damon Lindelof’s advice to him: “Tell your story. Stick to your guns.”

Monaghan, who says FF is “not as sophisticated” and mythology-rich as Lost, signed on without a script or a specific character description. “He took an enormous leap of faith,” says David Goyer.
