Chris Evans seemed to be perfectly cut out for the role of Steve Rogers aka Captain America in the MCU. It’s hard to believe that Marvel actually struggled to convince him to take on the role when they offered it to him.

In an exclusive clip released by celebrity news outlet PEOPLE, Marvel casting director Sarah Finn talks about how Evans was having serious doubts about becoming an international star.

“When we really distilled the core qualities that we wanted out of Captain America, I think there is really a moral fiber to him that really isn’t something you act, that it’s something that you need to possess,” Finn says in the clip about looking for the right actor to play the hero.

Finn adds, “Chris Evans was someone who seemed to inhabit all of those qualities the most. So everyone was in love with the idea of Chris — except Chris.”

As for Evans, he realized that taking on the role would mean a dramatic lifestyle change.

“The only reason there was hesitation, to begin with, is because of the commitment,” Evans shares. The actor adds, “It’s a big movie and if it succeeds there’s a change, a lifestyle change. And if it fails, it’s a whole other can of worms.”

While Evans found it hard to believe that he can actually give justice and commit to the role, another MCU star was definitely rooting for him.

His co-star Robert Downey Jr., who began playing Tony Stark aka Iron Man in 2008’s titular film.

“Once he committed, he committed 1000 percent,” Downey says in the clip. “He stands there, tells the truth and then he kicks a—.”
