Who: Oscar Isaac as Marc Spector/Steven Grant

Moon Knight Explained

Playing someone with dissociative identity disorder, Isaac finds himself wearing multiple masks — both literally and figuratively — in this series.

When we meet his character, he believes that he’s a mild-mannered museum gift shop employee named Steven Grant, but he soon learns that he shares a body with a mercenary named Marc Spector. “As Steven and Marc’s enemies converge upon them, they must navigate their complex identities while thrust into a deadly mystery among the powerful gods of Egypt,” per the show’s official logline.

Marc is all business, while Steven is more likely to make you laugh… whether he means to or not.

“I thought it was a different kind of humor to bring into the MCU,” Isaac tells TVLine, adding that he based Steven’s very specific accent on the work of British comedian Karl Pilkington (An Idiot Abroad). “Robert Downey Jr. came in [as Tony Stark/Iron Man] and did the whole self-aware thing just so well. He did it so brilliantly. And it feels like that culminated with Deadpool having the ultimate self-awareness. It felt like we couldn’t keep repeating that, so how about we go back to this idea of this character who doesn’t know he’s being funny?”
