MOON KNIGHT Writer Jeremy Slater Opens Up About Leaving the Series Over Creative Differences

When Moon Knight hit Disney+ in 2022, Marvel fans were excited to see Oscar Isaac dive into one of the MCU’s strangest and darkest characters.

The series earned strong reviews and currently sits at 86% on Rotten Tomatoes, but even with all the praise, plenty of viewers walked away feeling like the show lost its footing by the end.

Now, Moon Knight head writer Jeremy Slaterhas revealed that some of those issues may have stemmed from major creative disagreements during production.

Speaking with The Hollywood Reporter, Slater confirmed that he ultimately exited the project because he and one of the directors had completely different ideas about what the show should be.

"I certainly don’t want to say anything bad or negative about Marvel or my time there. They took a chance on me, and they let me assemble a really great writers’ room. I was really, really proud of the work that we did.

“The end result was I left the project over creative disagreements with the director. The two of us simply had very different visions on what the show should be about.

“Ultimately, he won that creative battle, so I stepped away. He then brought in his own team of writers to create a show that was his vision and the story that he wanted to tell."

Marvel’s Disney+ era at that time had a pretty unusual production structure. Instead of traditional TV showrunners steering the ship from start to finish, Marvel approached these series more like films with rotating directors and a “head writer” position that didn’t carry full creative control.

That setup reportedly created some messy situations across several projects, and Moon Knight seems to have been one of them.

The series definitely had moments that worked incredibly well, especially Isaac’s performance as Marc Spector and Steven Grant. But once the story shifted into the asylum sequences late in the season, a lot of fans started scratching their heads. Whether the confusion was intentional or not, many viewers felt the finale didn’t fully stick the landing.

Slater also talked about how unusual the experience was compared to a standard television production.

"It certainly was not a traditional showrunner experience where the writer is the boss. That was not remotely my experience at the time, but I can’t speak to what the process is like now.

“I know a lot of writers who have gone through the development process at Marvel and have had great times. It’s just that the pairing of writer and director is always really, really tricky.

“When it works — like I think it did on Mortal Kombat II with Simon McQuoid — it is magical and wonderful. But when it doesn’t work, it’s probably really frustrating for everyone involved."

While Slater didn’t name the director involved, many fans assume he’s referring to Mohamed Diab, who played a major role in shaping the final version of the series.

As for the future of Moon Knight, things are still pretty murky. Marvel hasn’t announced a second season, and Marc Spector remains one of the MCU’s biggest loose ends. Isaac has previously said he’d be interested in returning for a potential Midnight Sonsproject, but for now the character is sitting in limbo.

Slater also reflected on another painful comic book experience during the interview: 2015’s Fantastic Four reboot.

The writer explained that he wasn’t aware of any chaos happening during production and genuinely believed the film was going to launch a huge new franchise. According to him, the version audiences eventually saw barely resembled the script he originally worked on with director Josh Trank.

"It wasn’t until I was sitting there in that first audience and realizing, 'Oh no, something happened here. There was nothing in there that remotely resembled what I had set out to do.'"

He added: "But there was a good two-year period there where I was walking around very confident. I was like, 'You guys, just wait for Fantastic Four. We’re the next Christopher Nolan. We’ve got the next [Dark Knight] trilogy on the way,'" Slater recalled.

"You always go in with the highest of hopes and the best of aspirations. But sometimes the projects don’t turn out the way that you dreamed about or envisioned."

That version of Fantastic Four famously went through major rewrites and reshoots, with Simon Kinberg stepping in during development. The final movie ended up becoming one of the most criticized Marvel adaptations ever made.

Since then, Slater has rebounded in a big way. He’s currently involved with the Mortal Kombat franchise and was also one of the writers recruited by James Gunn and Peter Safran for the early DC Studios writers’ room. Even so, fans still haven’t heard much about what projects he may actually be developing for DC.

Looking back at both Moon Knight and Fantastic Four, it’s clear Slater has had a front-row seat to how dramatically superhero projects can shift once multiple creative voices start pulling in different directions.
