Marvel—faced with the tricky proposition of getting its audiences excited for the adventures of Moon Knight, a superhero best known for mental illness and driving a cab—continues to load up its upcoming Disney+ series about the character with high-profile talent. The producer has already tapped Oscar Isaac to star as the title character, which should get a fair number of butts in seats, and will now flesh out the show’s cast with a regular role for Ramy’s May Calamawy. Per Deadline, Calamawy—who plays Ramy Youssef’s sister Dena on the Hulu series—has been cast in an undisclosed role. (Moon Knight has a few different supporting characters and love interests over his 40-year history as a character, but none you’re likely to recognize by name.)
