The Serenity spaceship originally derived from the imaginations of "Firefly" director Joss Whedon, visual effects supervisor Loni Peristere, and production designer Carey Meyer. In the fictional sci-fi series, Serenity's main propulsion system utilizes a fusion explosion behind the ship for increased speeds, and it looks like a firefly. Adrian Drake's Serenity model features a light-up "Firefly drive" in the rear and cargo bay within.
