Moon Knight: Oscar Isaac's Brother Helped Him Play Multiple Personalities
To play dual personalities Marc Spector and Steven Grant for Moon Knight, Oscar Isaac enlisted his brother for help. Isaac has conquered Star Wars and Dune, and with the Disney+ series Moon Knight, he boards the MCU. He was first cast in the role of Marc Spector in late 2020, and he will officially make his onscreen debut next week. Moon Knight marks a new kind of Disney+ show for Marvel, in that it's a bit darker than previous efforts and centers on a brand new character who has yet to debut in the movies. It also stars May Calamawy and Ethan Hawke, who takes on the role of mysterious villain Arthur Harrow.
