The Avengers descended on Comic-Con over the weekend to debut the first footage from the upcoming sequel, Marvel's Avengers: Age of Ultron. ET's Rocsi Diaz caught up with stars Robert Downey Jr., Mark Ruffalo and Chris Evans for a hilarious interview about the flick and the hijinks ensued.

With three Iron Man movies, the first Avengers and now the sequel, RDJ is a Comic-Con regular. The frequent appearances to San Diego for the annual convention feel like old hat to the 49-year-old actor.

"You do what you're supposed to do then you go back to your hotel room and then you do what your wife says and then you go home," he jokes.

And he's plenty busy at home too! Downey Jr. and his wife of nearly ten years, Susan Downey, are expecting a baby girl this November.

As far as promotion for the Avengers sequel goes, he and co-star Mark Ruffalo know better than to spill any juicy details.
