Firefly is an American science fiction television series created by writer/director Joss Whedon, creator of Buffy the Vampire Slayer and Angel, under his Mutant Enemy Productions. Its naturalistic future setting, modeled after traditional Western movie motifs, presents an atypical science fiction backdrop for the narrative. Whedon served as executive producer, along with Tim Minear. Firefly premiered in the United States and Canada on the FOX network on September 20, 2002. It was cancelled after only eleven of the fourteen produced episodes were aired. Despite the series' relatively short life span, it received strong sales when it was released on DVD, and has impressive fan support campaigns. It won an Emmy in 2003 for "Outstanding Special Visual Effects for a Series". The post-airing success of the show led Whedon and Universal Pictures to produce a film based on the series, titled Serenity after the fictional Firefly-class spaceship featured in the show. The series is set in the year 2517, after humans have arrived at a new star system, and follows the adventures of the renegade crew of Serenity, a Firefly-class spaceship. The ensemble cast portrays the nine characters who live on Serenity.
