Oscar Isaac has recently received critical acclaim for his performance in the Marvel Studios’ Moon Knight. The Golden Globe Award nominee delivered an impressive portrayal of dual personalities Marc Spector and Steven Grant that was one for the books. 

Isaac had a significant role in the movie and production as he not only acted in it but was also an executive producer. Juggling all of these may have taken a toll on anyone, but Isaac had familial help with him.

What is ‘Moon Knight’ about?

Moon Knight follows a Jewish-American mercenary who battles dissociative identity disorder, bringing him into contact with several alter egos, including Steven Grant. Marc Spector seemingly leads a double life, with half of his life being the avatar of the Egyptian moon god while the other half of him being a well-mannered gift shop employee.

When the identities meet, there is visible tension, but they eventually warm up to each other and help each other get out of conflicts. Isaac plays the various roles of Spector/ Moon Knight and Grant.

In an interview with RadioTimes, the actor admitted that he didn’t expect that the role would be as demanding. When figuring out how to take on the different roles, Isaac decided to differentiate each character with different accents; thus, Grant’s British accent was born. The studio very much welcomed the decision to give the characters different accents despite the comics dictating otherwise.

Portraying different identities all at once can be taxing on even the best, which is why Isaac decided to enlist his family’s help to play the roles at once. In an interview with Vanity Fair, Isaac revealed that his brother Michael Hernandez had a role in the series.

The production required a stand-in for the actor to act opposite when sharing scenes with himself, and as it turns out, Isaac knew the best person for the role. “It was wild to have him on set and to play off of. He’s a great actor, and we share DNA, so he was very helpful. I couldn’t have done this with anyone else,” he gushed.

Isaac admitted that playing the various characters was challenging but said he and his brother already had chemistry which they relied on to get through it effectively. “We improvised sometimes together. It was so much fun,” he said.

Interestingly, Moon Knight isn’t the first production the Hernandez brothers worked on together. The pair also appeared on screen together in 2020 for the short film The Letter Room, which received critical acclaim. Hernandez is a journalist, but he occasionally dabbles in the acting industry from time to time.
