Rivals roughhousing on the red carpet? That’s nothing new for Thor and Captain America! at Comic-Con in San Diego, Calif., Saturday Chris Hemsworth got into a friendly rumble with his Avengers: Age of Ultron co-star Chris Evans. The Australian movie star insisted, “He started it! He pushed me first! You saw it!” Evans and Hemsworth had just walked off-stage after debuting the first footage from the movie. Hemsworth summarized the sequel to 2012’s The Avengers as “epic,” and attendees certainly agreed. “This was on another level. It was amazing. You all of a sudden realize what we’re a part of and what we’re involved in and what it means to those fans.”
