As crowded as the Marvel Cinematic Universe already is with characters after 10 years of storytelling on the big and small screen, there are still countless Marvel heroes and villains who haven't arrived yet. Among those, one of the characters who's seen quite a bit of interest from fans and filmmakers alike is Moon Knight, the supernatural vigilante who first appeared as a villain in 1975 before being retconned as a dark hero with psychological issues. Marvel Studios head Kevin Feige has expressed at least some interest in introducing the character to the MCU, and now an actor who's already made a brief appearance in the universe is ready to put on the costume.

Ross Marquand, best known to genre fans for his role as Aaron on The Walking Dead, made a brief cameo appearance in Avengers: Infinity War this year, taking over Hugo Weaving's role as a the Red Skull, who was serving as custodian of the Soul Stone on Vormir. Marquand lent his considerable voice talents to that role, but because it was the Red Skull we never got to see his face. Speaking to AiPT at Connecticut's ComiCONN over the weekend, Marquand was asked if there's any other Marvel character he'd like to spend a bit more time with. Moon Knight was right at the top of the list.

"Oh yes — Moon Knight! It’s tough because a lot of my friends have said Moon Knight is essentially just Marvel’s answer to Batman, but I don’t agree with that. I agree that there are similarities, but Moon Knight was a mercenary, kind of a gun for hire who didn’t really have much regard for people before he had his moment of awakening, I guess. And Bruce was always a good guy–even as a kid, he was torn by revenge, but he wasn’t this bloodthirsty killer like Moon Knight was," Marquand said. "So I think that, coupled with what they’ve been doing the last 15 years with the character–going into the dissociative identity disorder, really calling in to question if everything happening is all in his head, is he actually a vigilante killer or did he die in Egypt? It brings up a slew of questions, and that to me has never really been delved into in any comic book character before–the idea of, is any of this actually happening? Is he crazy? Is he killing good people? Is he actually dead in Egypt? Those are such amazing questions and I don’t feel like any comic book series before or since has really tapped into that. So for me, playing a crazy superhero would be awesome. So Moon Knight, Moon Knight for sure."

Marquand's not the first person involved with the MCU who's expressed interest in seeing Moon Knight, whose real name is Marc Spector, but who has also taken on several different alter egos throughout his 43-year history. Steven S. DeKnight, who served as showrunner on the first season of Netflix's Daredevil series, expressed interest on devoting a series to the character just months ago, and last year Guardians of the Galaxy writer/director James Gunn expressed interest in tackling the character when he's done with that franchise.

Then there's Infinity War co-writer Christopher Markus, who said he'd love to see the character make it to the screen while also acknowledging the characters inherent complexity, which includes both dissociative identity disorder and the fact that he got his superpowers when he was killed in the desert by a former mercenary ally and then brought back to life by the Egyptian god Khonshu, who sometimes has a major impact on his stories and sometimes is barely mentioned.

“Somebody should make a really good Moon Knight movie, but it’s complicated,” Markus said last month during an interview on Kevin Smith and Marc Bernardin's Fatman on Batman podcast. “It's because he got really good later. At the beginning, he was kinda good but also kinda cheesy, and then later on he got kinda awesome, but the awesome part kind of needs the cheesy part to make sense, so it gets convoluted very quickly. But he’s Jewish, which is nice.”

Even if we do end up seeing Moon Knight appearing in live action (he's a character who might be better suited to something like Netflix than a feature film), it's not clear at all how long it would take to make that happen, particularly since Feige offered a very speculative timeline ranging as far out as 15 years (Marvel's not going anywhere, folks). The MCU is a constantly changing place, though, particularly in the wake of events like Infinity War, so there's always a chance it could happen sooner than we think. Plus, if Marvel decides to put Moon Knight in development, they already have Marquand's number.
