CRI听力:'Avengers'Star Cast Unveil 1st Glimpse Of Sequel At Comic-Con

Several members of "The Avengers" have descended on Comic-Con to debut the first footage from the upcoming superhero sequel.

"Iron Man" star Robert Downey Jr. and other members of the star-studded cast for "The Avengers: Age of Ultron" were on hand over the weekend in the U.S. city of San Diego.

The team unveiled the first glimpse of their next on-screen adventure to the 6,500-plus attendees at the Con.

Downey Jr. promised a perhaps darker take on the superheroes than in the blockbuster first team-up.

"The first one is about can we get these folks together. This one is can we keep them together given the immensity of the challenge. And I think it also goes a little deeper into their fractures in their psyches."

The teaser footage ended with a bleak scene of all the Avengers fallen with a haunting close up of Captain America's shield split down the middle.

The presentation ended with a brief appearance by actor Josh Brolin, who voices the alien villain Thanos in both "Age of Ultron," which is set for release next May, as well as "Guardians of the Galaxy," the cosmic Marvel romp that comes out in the U.S. on Friday.
