Disney has confirmed in an investors' conference call that Joss Whedon will return as the director of The Avengers sequel. Disney also confirmed rumors that Whedon is developing a live-action show for ABC that takes place within the Marvel universe.
The movie deal is a 3-year exclusive, meaning the latest an Avengers movie could be made with Whedon at the helm is sometime in 2015.
ABC has been rumored to be eying a Hulk TV series much like the classic superhero show. However, it's believed that Whedon will be working on something else entirely; Guillermo del Toro is attached to the Hulk project instead.
