Pic and story from EW:
“If you didn’t recognize Carell at first sight, you’re not alone. “We just had our first test [screening], and not everybody recognized Steve. He is aged [for the film], and his face is changed, and his physicality changed,” says Miller, who explains that the unlikely casting of Carell as a killer is an important part of making the character feel authentic. “If I say I’m going to make a movie about a guy who’s a schizophrenic murderer, there are probably a dozen actors who would immediately appear on anybody’s casting list. And Steve would not be on any of those lists. And that’s a good thing. Because it’s unexpected… John DuPont was a character who nobody thought was capable of doing something as horrible as he did. And I did not want to cast somebody who would feel dangerous in that way.”
