The Marvel Watchlist You Need Before Avengers: Doomsday

For most of last year, the answer to "what do I need to watch before Avengers: Doomsday" has been an unhelpful shrug: everything. Thirty-plus movies, a dozen-plus shows, two decades of continuity, unfortunately we concur that we might not have that kind of time before December.

Then Disney did something useful. Under a section on Disney+ called "Countdown to Avengers: Doomsday," the studio quietly posted its own official essential-viewing list. 14 movies and one series, hand-picked as the required reading before Robert Downey Jr. walks back onto a Marvel set as Victor von Doom. It's the same instinct that drove Marvel's cast reveal back in March 2025, when the studio spent five and a half hours unveiling the Doomsday roster one director's chair at a time. Announcing 27 actors, including the surprise return of the original Fox X-Men cast: Patrick Stewart, Ian McKellen, Kelsey Grammer and Alan Cumming.

Disney’s sequencing is not random. The studio seems to be asking to rewatch it thematically, in four rough movements. First, the X-Men legacy.  Second, the fracture of the original Avengers and third, the newer generation : Sam Wilson, Yelena Belova, the Thunderbolts who make up the actual working roster Doomsday leans on. And finally the multiverse machinery that lets all three of those groups occupy the same movie without the plot collapsing under its own weight. 

Disney's list is a good skeleton. It is not, by its own admission and by immediate fan consensus, complete. It did not have Captain America: Civil War, no Black Widow, no Age of Ultron and absence of The Marvels, despite it being the film that actually reintroduces Kelsey Grammer's Beast. 

So here is the order in which to watch the movies, with the most-cited fan additions slotted into the exact spots where they belong. Watch this order, Disney's list and fan additions together and the shape of the story becomes obvious well before you reach the theatre.

This is the Xavier and Magneto walking back onto screen after twenty-six years away, played by the same two actors. It's also the film generally credited with proving comic-book movies could be taken seriously in the first place.

The high point of the original trilogy, and the film that gives Alan Cumming's Nightcrawler his signature entrance. Nightcrawler's teleporting assault on the White House opens the film cold, with almost no dialogue, and it remains one of the best set pieces the franchise has ever produced. Alan Cumming stepping back into the role more than twenty years later is one of the stranger and more delightful facts about the entire Doomsday casting process.

This is where Kelsey Grammer's Beast first appears and Beast is confirmed for Doomsday. 

Not on Disney's official list, but the fan-consensus finale for this cast, the film that sends Patrick Stewart's Xavier and Hugh Jackman's Wolverine off with the weight their two decades on screen earned. It's also the direct tonal and emotional bridge to Deadpool & Wolverine, which spends real time acknowledging what happened here. Because Wolverine himself isn't confirmed for Doomsday in this specific continuity, Logan functions less as direct prep and more as closure 

Steve Rogers, before the modern world catches up to him. Maybe the Steve-and-Peggy romance carries more weight in Doomsday than anyone previously assumed.

The original blueprint every team-up movie since has been quietly copying. Watching it again now, more than a decade later, it's remarkable how much of the modern shared-universe playbook was invented in this one film almost by accident. Every ensemble structure choice Doomsday makes, from staggered hero introductions to the climactic wide shot of the team standing together, traces back to a formula this movie set in stone.

The movie is the first real crack in the original team and the film that introduces Vision. It's also the film most frequently cited by fans as the single biggest gap in Disney's official list, given how directly it seeds the Scarlet Witch and Vision material that later pays off across the multiverse era.

The fracture becomes a rupture here and it is the film that decides who trusts whom for the next decade. 

Introduces Yelena Belova and Red Guardian, both confirmed Doomsday cast and both central to the Thunderbolts* roster the film draws from. One tip that keeps circulating: watch the movie, but hold off on the post-credits scene until after Endgame.

The film where the fracture from Civil War gets tested under the worst possible circumstances and the one where Thanos finally makes good on the threat every prior movie had been quietly building toward. 

The end of the Infinity Saga and more importantly for our purposes, the actual starting line for the story that eventually leads to Doomsday. Everything after this film exists in the world Endgame leaves behind.

Sam Wilson's entire journey to picking up the shield and a prerequisite for understanding Captain America: Brave New World later on this list. The show spends real time on what the decision costs him personally and politically, groundwork that Brave New World assumes you've already absorbed.

Low profile and yet it quietly connects more of the confirmed Doomsday cast than people tend to give it credit for. Worth the six-episode investment.

The one show that does an enormous amount of narrative heavy lifting to earn that spot. This is where the multiverse concept actually gets its rules, its stakes and its central mystery, all of which the rest of the saga has been quietly building on ever since.Its season two finale in particular is widely expected to be central to how Doomsday justifies putting decades of separate continuities in the same room.

A confirmed Doomsday fighter gets his introduction here. That scene, involving the Ten Rings themselves, is one of the more direct breadcrumbs toward the current status quo heading into the new film.

Tom Holland's Spider-Man being on Disney's list is widely read as a signal about the multiverse mechanics the new film will lean on. It's also the first film in the saga to prove the multiverse could work as pure spectacle rather than theory and TVA bureaucracy.

Namor's introduction and the uneasy, tension-filled history between Wakanda and Talokan that Doomsday is very clearly building on. Pay attention to how that alliance ends.

The movie gives Cassie Lang real, lasting consequences before any bigger team-up movie can reasonably ask more of her character. It also treats the Quantum Realm as a genuine threat rather than a plot device, groundwork that later films quietly build on.

The movie reintroduces Kelsey Grammer's Beast ahead of Doomsday with a mid-credits scene that many consider a direct breadcrumb.

Sam Wilson, fully Captain America, dealing with the political weight that comes with the shield and the film that starts assembling pieces later picked up by Thunderbolts*.

The film that formally, mechanically welcomes the Fox X-Men universe into the MCU proper. Everything in the X-Men block earlier on this list functions as homework for this movie specifically, and this movie in turn functions as homework for Doomsday.

Wanda Maximoff, consumed by grief and the Darkhold, spends the film tearing through parallel universes hunting a teenager whose only power is the ability to travel between them, which is exactly the kind of ability the Doomsday trailers suggest is now driving the plot. The Illuminati sequence in the middle of the film, where an entire alternate universe's council of heroes gets wiped out in under a minute, is the first time the MCU actually shows what happens when two realities touch. 

The team-up that forms the actual backbone of the Doomsday roster. A scavenged team of morally compromised castoffs, Yelena, Red Guardian, Ghost, John Walker, Bucky, gets thrown together by Valentina de Fontaine and immediately turned against Bob, an unstable superhuman whose grief and self-loathing literally consume him from the inside and turn him into the Void. 

Marvel has said outright, in interviews and press materials alike, that this film flows directly into Doomsday. Reed, Sue, Johnny, and Ben are half the poster.

Twenty-four titles with one very obvious beast-shaped hole where The Marvels should be. Doomsday's whole plan reportedly hinges on universes colliding without warning,  so it seems only fair that you walk in already knowing who's on which side of the collision. Skip a title and you will arguably spend December mistaking a grudge for a friendship or a friendship for a grudge, while everyone around you nods along.

If you are mapping this onto an actual calendar between now and December 18, the math is forgiving: roughly two titles a week gets you through the entire list with a month to spare. Whatever gaps are left after all that, Doom himself is presumably going to fill in. That's rather the point of the movie. 

Happy Marathoning!
