HE AVENGERS DIRECTOR JOSS WHEDON OPENS UP ABOUT EMPOWERING WOMEN AND UNLIKELY HEROES: "GOD, MY WHOLE CAREER HAS BEEN ABOUT THAT!"

Interview Airs Sunday, April 29 on "CBS Sunday Morning With Charles Osgood"

Best known for small, quirky television shows - like the cult hit Buffy The Vampire Slayer -Joss Whedon may seem an unlikely choice to write and direct a film that packs not only a team of Marvel Comics' mightiest superheroes, but also some of Hollywood's biggest names. But The Avengers, which opened this week overseas and is set to debut in the U.S. on May 4, is already generating the kind of acclaim and box office success that has Disney and Marvel Comics seeing green (and not just because of the Hulk).

This weekend, CBS News correspondent John Blackstone catches up with Whedon, who discusses the challenge of taking on a potential blockbuster, as well as how empowering women has been a theme throughout his work.

"I loved the idea of a girl going into a dark alley, and a monster comes, and then she just aces him," Whedon tells Blackstone. "It's like, you want to see the tiny person suddenly take control. God, my whole career is basically about that!"

The full interview - which includes clips from the film - will broadcast Sunday, April 29, on the CBS SUNDAY MORNING WITH CHARLES OSGOOD (9:00-10:30 AM/ET) on the CBS Television Network. Rand Morrison is the Executive Producer.
