Debunking Marvel's Phase Four Myths

The Marvel Cinematic Universe’s Phase Four promised a new era—fresh heroes, bold stories, television series woven directly into the movies. Fans dove in for the spectacle, for the thrill of seeing characters like Wanda Maximoff or Shang-Chi headline their own adventures. And for the first time, television wasn’t just a side story—it was central, with Disney+ premieres like WandaVision and Loki attracting millions of viewers around the globe. But as the lineup of movies and shows expanded, so did the wave of rumors, leaks, and outright misinformation that swept across the fandom.

One of the biggest misconceptions to emerge was about the role of the multiverse. After Loki’s first season finale in 2021, many fans claimed that every Marvel project going forward would directly tie into alternate universes, with social media posts and forums insisting that every cameo, every plot twist, was secretly a multiverse event. In reality, Marvel Studios developed a “rule book” for how the multiverse would operate, managed by executive producers like Kevin Wright and Stephen Broussard, and coordinated across WandaVision, Loki, and What If…?. The multiverse was central to some projects—like Doctor Strange in the Multiverse of Madness or Spider-Man: No Way Home—but a large portion of the Phase Four slate remained grounded in the main continuity, Earth-616.

This confusion was fueled by Marvel’s own marketing. At San Diego Comic-Con in July 2019, Kevin Feige announced Phase Four’s slate, highlighting connections between WandaVision, Loki, and Doctor Strange in the Multiverse of Madness. But during production delays caused by the COVID-19 pandemic, Marvel shuffled release dates. Black Widow, originally set to introduce Valentina Allegra de Fontaine, ended up premiering after The Falcon and the Winter Soldier, leading fans to speculate wildly about secret timeline changes and missing scenes. Julia Louis-Dreyfus’s appearance as Valentina was supposed to debut in Black Widow, but because of the pandemic, her character actually showed up first in The Falcon and the Winter Soldier.

Another rumor that spread rapidly involved which projects counted as “canon.” Fans debated whether the animated series What If…? and the Marvel Studios Special Presentations, like Werewolf by Night, were truly part of the main MCU timeline. Marvel Studios president Kevin Feige clarified that only projects developed by Marvel Studios during the first four phases were part of the “Sacred Timeline.” However, with the multiverse concept, outside timelines could now “crash or converge” with the main universe, giving rise to more confusion and heated online arguments.

The scale of Phase Four’s expansion also became a source of misinformation. In 2021 alone, Marvel Studios released four films and five television series. Fans speculated that this surge in content was evidence that Marvel had lost control of its storytelling, or that executives were rushing out projects without a plan. In truth, the rapid release schedule was a response both to the demands of the global streaming market and the delays caused by pandemic shutdowns. Kevin Feige stated that many of these stories were largely standalone, or continued directly from Avengers: Endgame, rather than all being intricately interconnected.

One of the most persistent myths centered around character appearances. When Spider-Man: No Way Home brought back Tobey Maguire and Andrew Garfield as alternate Spider-Men, rumors exploded online that every past Marvel character could now appear in the MCU. Fan-made lists of supposed cameos circulated, with some claiming that major X-Men, the Fantastic Four, and even Netflix’s Daredevil were about to debut in every upcoming project. In reality, No Way Home’s inclusion of Maguire and Garfield was carefully planned and limited. Early drafts of the script had nearly every major character from previous Spider-Man films, but the creative team chose to narrow the focus to avoid excessive fan service.

The idea that the multiverse meant “anything goes” was reinforced by the way Marvel started using designations like Earth-616 and Earth-838. Some fans misinterpreted these labels as confirmation that the MCU was now identical to the comic book multiverse. In fact, Earth-616 was a term adopted for the MCU’s main timeline beginning with Doctor Strange in the Multiverse of Madness, but Marvel Comics had previously designated the MCU as Earth-199999. The use of “616” was mostly for in-universe clarity, not a merger of comic and movie realities.

Social media became a breeding ground for leaks and hoaxes about future projects. Multiple accounts posted lists of “leaked” plot details for Doctor Strange in the Multiverse of Madness, including false claims about appearances by major mutants, the Fantastic Four, and even Tom Cruise as an alternate Iron Man. In reality, the Illuminati featured characters like Patrick Stewart’s Charles Xavier, Hayley Atwell’s Captain Carter, Lashana Lynch’s Captain Marvel, Anson Mount’s Black Bolt, and John Krasinski’s Reed Richards. Most of these actors played alternate versions of their characters, not direct ports from their previous franchises.

Some misinformation was driven by Marvel’s own penchant for secrecy and surprise. For example, the mid-credits scene of Eternals introduced Harry Styles as Eros—Thanos’s brother—fueling speculation that the character would play a major role in the next phase. In practice, these cameos were teasers, not guarantees of future plotlines, but that hasn’t stopped rumors from spiraling into accepted fan “facts.”

The introduction of Disney+ series led to another wave of misunderstandings. Fans debated if one had to watch every single show to keep up with mainline Marvel movies, a phenomenon dubbed “Marvel homework.” Critics argued that the franchise had become confusing and inaccessible to new viewers, while others, like Dais Johnston of Inverse, pushed back, stating that each project could still be enjoyed as a self-contained story. The idea that “homework” was required became a kind of folklore, even as Marvel Studios tried to keep most stories accessible.

Disputes over representation also became fertile ground for misinformation. When Loki’s Disney+ series stated that Loki was bisexual, some online voices claimed that the show was now fully “pansexual,” or that future movies would be “super gay,” based on offhand comments from creators like Taika Waititi during the Thor: Love and Thunder press tour. After the movie’s release, fans debated whether this promise had been delivered, with some expressing disappointment over the amount and depth of actual LGBTQ+ representation.

Production rumors turned into full-blown misinformation campaigns when it came to casting. At various points, fans insisted that certain actors were “confirmed” for future Marvel projects based solely on rumors or wishful thinking. For example, John Krasinski’s appearance as Reed Richards in Doctor Strange in the Multiverse of Madness was a one-time casting based on fan proposals, but many online sources reported it as the beginning of a new Fantastic Four franchise.

Another persistent myth was that the multiverse allowed Marvel Studios to “erase” or “fix” controversial storylines from earlier films, including claims the studio would use the multiverse to bring back dead characters or undo unpopular choices. While Phase Four’s multiverse saga did allow for alternate versions of characters—such as the various Lokis in Loki or the three Spider-Men in No Way Home—the main MCU continuity remained intact. Marvel’s creative team, including Michael Waldron, carefully established that changes in one timeline didn’t overwrite the main universe, but instead created branched realities.

The role of cameos became a flashpoint. When Doctor Strange in the Multiverse of Madness featured the Illuminati from Earth-838, fans speculated that any character who had ever appeared in a Marvel film could now cross over. In reality, decisions about which characters to include, such as John Krasinski’s Reed Richards or Patrick Stewart’s Professor X, were made to serve the story and avoid overloading the narrative with references.

Misinformation also surrounded the reasons for production delays and scheduling changes. Some claimed that Marvel Studios was panicking or losing control due to “Marvel fatigue” and declining box office returns. In fact, the COVID-19 pandemic caused a cascade of delays, forcing Black Widow and other movies to be rescheduled multiple times. The decision to pivot Black Widow to a simultaneous theater and Disney+ Premier Access release led Scarlett Johansson to file a lawsuit against Disney, claiming breach of contract—a legal dispute that was widely reported on, but also misrepresented in some fan spaces as evidence of deep internal fractures at Marvel.

Rumors about pay and creator recognition also circulated. Joe Casey, co-creator of America Chavez, publicly stated he received no compensation for the use of his character in Doctor Strange in the Multiverse of Madness. This sparked online speculation that Marvel never pays its creators, when in fact the compensation and credit system is complex, and some creators do receive payment or acknowledgment, while others do not.

Another topic mired in misconception is the accusation of “whitewashing” and lack of diversity within Phase Four. While the MCU did face criticism for its earlier phases—where only two of the first 23 films were directed by people of color and only one by a woman—Phase Four brought more diversity, with films like Shang-Chi and the Legend of the Ten Rings and Black Panther: Wakanda Forever featuring leads and creative teams of color. Debates online have sometimes downplayed these shifts, or, alternatively, overstated the degree of change within a single phase.

The complexity of the multiverse itself became a source of misinformation. Some fans conflated Marvel’s cinematic and comic continuities, or incorrectly stated that every Marvel movie and TV show outside the MCU was now part of the same universe. In fact, Marvel Studios clarified that only their own projects were considered part of the Sacred Timeline, but that outside timelines existed in the larger multiverse and could “crash or converge” with the main MCU.

Visual effects artists also became a focal point when stories surfaced about working conditions at Marvel Studios. Reports from Vulture and Collider described artists working “seven days a week, averaging 64 hours a week on a good week,” and being asked to make significant changes to films just weeks before release. These stories fueled rumors that Marvel’s visual effects were declining in quality, although the real issue was more about management and last-minute changes than a lack of talent or effort.

Box office statistics were another area rife with misinformation. Some claimed Phase Four was a “flop” when, in fact, its seven films together grossed over $5.7 billion worldwide. While this was less than the peak era of Avengers: Endgame, it remained higher than almost any competing franchise.

There were also misconceptions about the MCU’s relationship with the military. While some films used military assets and received technical input, rumors circulated that every script required formal military approval. In truth, directors like James Gunn have explained that military approval is only needed when films use military equipment for free, and that the military is generally “pretty loose about it.”

Fan theories about upcoming “secret invasions” or hidden plotlines became so prevalent that many fans treated them as spoilers or leaks, only to be disappointed when projects like Secret Invasion or Armor Wars did not materialize in Phase Four, or were shifted to later phases due to creative changes and development delays.

The sheer volume of content led to debates about “Marvel fatigue.” Critics argued that too many interconnected projects risked turning off casual viewers, but defenders pointed out that the franchise had managed to keep consistency and quality despite the output.

The introduction of animation through Marvel Studios Animation led to speculation that every animated project was canonical, with fans debating the relevance of What If…? to live-action stories. Marvel’s approach was more nuanced—animated stories could influence the multiverse saga but were not always direct extensions of the live-action continuity.

Discussions about representation of women and LGBTQ+ characters were sometimes marred by misinformation about what had actually changed. While Captain Marvel (2019) was the first solo female-led film, Phase Four included projects like WandaVision and She-Hulk: Attorney at Law, sparking both praise and criticism about the depth and direction of representation.

Questions about the future of the MCU remain heavily debated within the fandom. Some claim that the multiverse is a narrative dead end, while others argue it provides limitless storytelling possibilities. The actual impact on long-term storytelling is still unfolding, as Marvel continues to expand its Multiverse Saga across Phases Five and Six.

One detail often overlooked is that Benedict Wong made more appearances in Phase Four than any other actor, starring or making cameos in three films and two television series.

So, with the MCU’s Phase Four in the rearview mirror, here’s the question the fandom is still wrestling with: does the embrace of the multiverse and the tidal wave of content make it easier or harder for fans to separate fact from rumor—and is that a bug, or a feature, of the Marvel experience?
