Moon Knight will follow Stephen as he comes to terms with the discovery that he has dissociative identity disorder, sharing a body with Marc Spector, a ruthless mercenary. As the two try to navigate their situation, they are challenged by a variety of sinister foes as they become embroiled in a mystery surrounding the gods of Egypt. Ethan Hawke, who appears in the trailer, is set to star as one of the series' villains although his actual character is still unknown.

Speaking to his role as Marc Spector, Isaac noted that the decision to join the cast of Moon Knight was one of the best risks he's ever taken. "I found so much room to do things that I've never done before and had been curious about and wanting to do. I could not wait to get to set, and it was the biggest workload I've ever had in my career and most challenging; by the sheer amount of stuff we had to do in eight months, and even yet, I couldn't wait to get to set and work."

Speaking to the show's darker tone and themes, director Mohamed Diab said, "My movies are hard, serious and about big topics, and I feel strongly that Moon Knight is going to be like that — it’s going to be entertainment but also heavy," Diab said. "At the same time, we’re being so creative with the jokes and with the action. As I keep saying to my wife: I can’t believe I’m funny in another language!"

Moon Knight premieres on Disney+ on March 30.
