Krasinski is making the rounds promoting his latest directorial effort, The Hollars, when he shared a story with Conan O'Brien. The actor was stepping into Cap's suit when, unexpectedly, Chris Hemsworth walked by in costume as Thor... and reality hit Krasinski like a star-spangled shield to the jaw. He tells Conan:

I went, 'I'm good. This is stupid. That's okay, I'm not Captain America.'

Hilarious. Listen, actors are paid to act, and become characters we don't expect to see on screen. John Krasinski is no less intimidating than Chris Evans is (or was) in real life. And if you saw Krasinski in Michael Bay's 13 Hours, you would have no problem believing him as a buff superhero in the Marvel universe.
