LOS ANGELES (AP) -- Joss Whedon has been hired on again as boss of Iron Man, Thor, Captain America and their superhero pals for a sequel to "The Avengers."

The news came Tuesday from Walt Disney Co. Chief Executive Officer Robert Iger, who said during a company earnings call that the filmmaker is returning to write and direct the sequel adapted from the Marvel Comics tales.

Iger also said Whedon is helping to develop a Marvel-based TV series for ABC. Marvel is a Disney subsidiary.

No details were provided on a start of production or release date for the sequel to "The Avengers," the year's biggest hit with nearly $1.5 billion at the worldwide box office.
