Firefly didn't even get to finish out its one full season on FOX back in 2002 but despite its early cancellation, the fans love for the crew of the Serenity never died. In fact, it got stronger. So much so that a feature film, Serenity, was released in theaters in 2005. Hope of a sequel has always had fans of Nathan Fillion, Gina Torres, and the rest of the memorable cast feeling shiny.
