Avengers: Doomsday Brings in Loki Writer Michael Waldron to Help Finish the Script of Movie That’s Been Filming Since April

by

The screenwriter Michael Waldron, known for creating Loki, is now aiding in the drafting of the script for Avengers: Doomsday. This indicates that the script for this upcoming Marvel ensemble film is still being worked on, despite the fact that principal photography has been ongoing since April 2025.

This announcement by Marvel Studios president Kevin Feige indicates that changes to the script are still being made during production, a method that has caused issues in recent Marvel Cinematic Universe (MCU) productions and leaves some uncertain about the film’s final product. Reminiscent of the problematic production of “Captain America: Brave New World,” which required significant reshoots and revisions following unfavorable test screenings, fans and experts are worried that Marvel might be repeating past errors on what is supposed to be one of its major blockbusters.

The Latest on Waldron’s Involvement

In a recent chat, Kevin Feige shared that Stephen McFeely, who co-writes scripts for movies like “Avengers: Endgame,” is spearheading the screenplay for “Avengers: Doomsday.” However, it appears that Michael Waldron is also lending his writing skills to the project now.

Every day, there’s a lot of progress being made on set, and it’s truly awe-inspiring to observe,” the head of Marvel stated. “It’s worth noting that the creator of Loki, Michael Waldron, is currently contributing to this project as well.

It appears that Waldron’s comeback implies the original script might need reinforcement, considering filming is still ongoing. Moreover, it’s concerning that fresh creative talent will be joining the production team for principle photography within the next three months, suggesting the script may not yet be finalized.

Waldron, recognized for his contributions to ‘Loki Season 1’ and ‘Doctor Strange in the Multiverse of Madness’, has had a varied history working with Marvel.

While Loki was initially applauded for its creative narrative (before shifting the series focus towards a female counterpart of the primary character), Doctor Strange in the Multiverse of Madness faced backlash due to inconsistent tempo and contentious character developments, specifically regarding Wanda Maximoff/Scarlet Witch. Critics also noted an apparent attempt to divert the film’s focus towards a fresh female character, America Chavez.

Concerns have been raised by followers of X regarding his participation, as one commentator jokingly remarked, “Michael Waldron writing the script for Avengers: Endgame… I guess we won’t be seeing Wanda anymore.

If Michael Waldron writes your favorites, you might just pass on Avengers: Endgame! Don’t test us, and I understand that the movie hasn’t got a script yet, but it’s never too early to consider replacing him from the project.

A supporter encouraged Marvel to rethink their decision, stating, “If having Michael Waldron write your favorites makes you pass on Avengers: Doomsday, then like and share this post.

Feige’s open statement that the script continues to develop on set, which he portrayed favorably, triggers concerns in light of Marvel’s recent track record.

Filming Without a Locked Script: A Risky Gamble

In April 2025, the movie titled “Avengers: Doomsday” commenced production at Pinewood Studios in England. The extensive cast features familiar faces from the Marvel Cinematic Universe and Robert Downey Jr., who takes on the role of the antagonist Doctor Doom. Early in April, Marvel confirmed the beginning of filming, while reports indicated that cameras had already started rolling by April 2025.

The movie will be premiered on December 18, 2026, having been postponed from its initial May 2026 scheduled date.

Revisions to the script during movie production are quite frequent in Hollywood, particularly in big-budget films such as this one, which is anticipated to mark the culmination of the Marvel Cinematic Universe’s Multiverse Saga. However, alterations at this stage could indicate more substantial problems.

As a devoted cinema admirer, I’ve got to clarify some recent buzz about Marvel Studios and their production methods. Contrary to certain rumors, I stand firm with Feige when he states they’ve never ventured into filming without a complete script. Yet, the ongoing refinements (industry lingo for tweaks and enhancements) and Waldron joining the team late in the game have raised some eyebrows, hinting that the screenplay might not have been as solidly established as suggested at the start of production.

In the past, this method has shown to be expensive. Experts in the field have observed that making changes at the last minute can result in increased costs, hasty visual effects, and plot inconsistencies – issues that have been prevalent in the Marvel Cinematic Universe following the end of Endgame.

Echoes of Captain America: Brave New World

The circumstances surrounding this project seem remarkably reminiscent of the film “Captain America: Brave New World,” released in February 2025. Much like that production, it underwent numerous changes following disappointing test viewings, involving multiple rewrites and reshoots. Originally filmed in 2023, the movie encountered delays as a result of these extensive alterations. It’s been reported that there were at least three additional photography sessions, with new characters being introduced during these reshoots to strengthen the storyline.

As a passionate cinephile, I can’t help but share some insights about a production I recently followed. Initially, the budget for this project grew substantially because of certain adjustments made along the way. Interestingly enough, Tim Blake Nelson, who brought The Leader to life on screen, disclosed that a significant portion of the initial script was reshot.

The film’s rocky production was highlighted by both critics and fans as a significant factor behind its varied response, with some labeling it as a “hodgepodge” of concepts that didn’t quite fit together neatly. Ebaster, in particular, disclosed 11 scenes that were modified or newly added during reshoots, featuring improved action sequences and plot alterations to better align with the overall Marvel Cinematic Universe.

If “Avengers: Doomsday” continues on this trend, it might encounter comparable criticism. This is particularly likely given its upcoming release and the high anticipation surrounding the Russo Brothers’ comeback, with fans eagerly awaiting their work.

Why This Doesn’t Bode Well for Marvel

The creative process for Marvel’s Phases 5 and 6 has faced setbacks, such as the lackluster storyline of “Ant-Man and the Wasp: Quantumania” and the commercial underperformance of “The Marvels.” Bringing in writer Krysty Wilson-Cairns during production could provide new perspectives, but there’s also a risk it may blur the original vision.

Several retakes might indicate that the initial storyline isn’t effective. It’s quite plausible that the studio is attempting to fix a flaw in an already weak structure, as filming continues.

Setting Doomsday with more than 60 characters and focusing on Doctor Doom as the main antagonist might lead to a complex, disorganized story – similar to the criticisms directed towards Multiverse of Madness.

While Feige may be optimistic, historical precedent indicates that last-minute adjustments can result in costly repairs down the line, which might also damage fan trust even more.

Looking Ahead: Can Marvel Course-Correct?

During the filming process, everyone is eagerly anticipating if Waldron and McFeely can produce a unified script for “Avengers: Doomsday” on schedule. The movie boasts high drama, but without a definitive storyline established early, there’s a chance it could follow in the footsteps of some of Marvel’s less successful recent productions. Fans longing for another “Endgame”-like triumph might want to adjust their expectations—or prepare themselves for possible additional filming later on.

At the moment, the fate of the multiverse remains uncertain, as Marvel’s ongoing script disputes seem to have no immediate resolution in sight.
