'Captain America: The Winter Soldier': Chris Evans Says Marvel Has 'Cracked The Code'

Hayley Atwell, Chris Evans weigh in on what makes Marvel movies work.

Marvel Studios has the golden touch. Fans know it, critics know it and happily the stars know it too, as we found out when we caught up with "Captain America: The Winter Soldier" actors Chris Evans (Steve Rogers) and Hayley Atwell (Peggy Carter) at the red carpet premiere in Los Angeles.

"For some reason, I don't know what Marvel's done, I don't know what code they've cracked... They always manage to make the movies good," Evans said.

Still, in Hollywood, good movies don't always equal happy casts. And in particular when working on a gigantic blockbuster, one couldn't necessarily expect anything but a general sense of exhaustion. Not so, says Evans.

"There's a real sense of comfort when you're working on these movies," Evans continued. "They're demanding, and they're exhausting, but knowing that they're going to be good movies is incredibly rewarding, and encouraging. Movies shouldn't be this easy to make successful. Somehow Marvel just has a Midas touch."

Atwell may have a smaller role in the films, having appeared in "The First Avenger" before making a shorter appearance in the sequel. But even she felt a sense of comfort, despite some initial worry.

"When you go into a machine like this, you can get sucked up, and I've done lots of theater, I felt like I was establishing myself in a different medium," Atwell said. "So to come into this initially, I had trepidations. But it was very clear when I met the director of the first one, Joe Johnston, and I met the producers, and then I met the writers, and then I met Chris [Evans] that it was a very relaxed environment, which I wanted to be part of."

You can see if Marvel's Midas touch paid off once again when "Captain America: The Winter Soldier" opens on April 4.
