According to the onlooker, it took about eight to nine times for Bettany, 45, and Olsen, 28, to perfect the scene.

The “Passenger” actor admitted to Fandango that he was intimidated when he saw Hemsworth on the set. “I was a little secretly intimidated. Chris Hemsworth, he’s so tall and handsome -- I had to go home and really look myself in the mirror.”

Meanwhile, Holland also shared his excitement in joining the “Avengers” franchise. According to the “Spider-Man” star, the experience was “mind-blowing.” In this clip from Marvel‘s official Twitter account, he recalled watching the first “Avengers” film with friends and he couldn’t believe that he is now joining the movie.
