Coming straight off the enormous success of 'The Avengers' movie, ABC has ordered a pilot for 'S.H.I.E.L.D.' -- the espionage and secret military law-enforcement agency in the Marvel universe. The network has also brought on the film's director and writer, Joss Whedon, to executive produce and pen the project alongside his brother, Jed. It will mark Marvel's first live-action television show and a return to television for Whedon, who has plenty of experience on the small screen with 'Buffy the Vampire Slayer', 'Firefly' and 'Dollhouse'. 'S.H.I.E.L.D.' made its debut in the comics in Strange Tales #135, which was published in August 1965. It has always been centered around director Nick Fury, played by Samuel L. Jackson in 'The Avengers'. There's no details yet on which superheroes we may see on the show but Whedon will have a plethora of characters to pick from the vast Marvel universe. It's probably safe to assume that he will be looking to differentiate the TV show's world from the film, with 'The Avengers' sequel slated for 2015.
