Joss Whedon has a master plan. Despite his full schedule, which includes promoting Much Ado About Nothing and prep for The Avengers 2, he's focused on TV. Whedon is developing a series based on Marvel's S.H.I.E.L.D with a new cast of characters.
The best thing about Whedon's new Avengers-adjacent TV show based on secret organization S.H.I.E.L.D. moving ahead at break-neck speed is that we get more and more details seemingly every week. This time, it's the confirmation of two more actors and tidbits on the characters they'll be playing.
