44 free Firefly trivia questions with answers. This Firefly trivia quiz is for Browncoats: the crew of Serenity and the actors who played them, the fourteen episodes and the three Fox never aired, the Unification War, Reavers, Companions and Blue Sun, and the 2005 film Serenity that answered the big questions and broke a few hearts. There is also a short bonus round on the real fireflies, the beetles that make cold light with luciferase and flash in sync in the Smoky Mountains. Questions run from easy ones any casual fan can answer to hard cuts about airing order, comics canon and production history that will separate the people who have watched it once from the people who own the box set. Every answer was checked against encyclopaedia entries before publishing.
