Buffy the Vampire Slayer creator Joss Whedon’s cult sci-fi series Firefly follows the adventures of nine crew members on the space ship Serenity, flying under the flag of the Anglo-Sino Alliance. Its single season on Fox had no nudity but featured the talents of boob-tube babes Gina Torres, Jewel Staite, Summer Glau, and racktastic redhead Christina Hendricks, future star of the AMC hit Mad Men. Firefly had firecrotch!
