Krasinski was at one time up for Captain America and recently talked about the effect Chris Hemsworth had on his process getting the role.
Whether it’s Marvel, or possibly even DC, if Krasinski continues to voice his desire for a role, it could very well happen.
Even with these big names, Marvel has also done a great job of turning other actors into stars, which is something that could have happened to John Krasinski had things gone differently.
How could it be good?” and then it ended up being one of the best ones, I think.
