Avengers: Doomsday is coming to theaters on December 18, 2026. If you have not kept up with the Marvel Cinematic Universe, the catch-up list looks like homework. A viral Instagram post put the total watch time at nearly 300 hours. Include the Disney+ series and the legacy Marvel projects tied to the multiverse, and the number climbs toward 350 hours. That is two straight weeks of nothing but Marvel.
According to reports, anyone planning to watch every movie, series, and special before the film would need around 330 watch hours, which equals 19,800 minutes. This calculation proves how massive the Marvel Cinematic Universe has become ahead of the film’s December launch. The long runtime has sparked new interest in shorter catch-up lists and selective rewatch guides that help viewers prepare without going through the entire franchise.
The 330-Hour Marvel Marathon Explained
If viewers want to watch Avengers: Doomsday and connect every detail, they will have to begin with Iron Man (2008). During that era, Netflix had not completed 18 months of its streaming service, and Instagram was still two years away when Tony Stark built a suit inside a cave. It was clearly a different era.
Now the MCU has grown into one of the largest entertainment production companies with 38 movies and more than 20 TV shows. A viewer needs more than 330 continuous watch hours to grasp and connect every detail, hidden reference, character arc, and storyline with the upcoming Avengers movie.
That is around 14 days of non-stop streaming, or about 55 days if you watch for at least 6 hours every day. If you start watching today and spend 2.5 hours daily, you would complete the franchise in time for Avengers: Doomsday.

Do you only have a weekend? One guide narrows it to nine movies that set up Doomsday directly:
- The Avengers (2012)

What You Can Skip
If you have wandered into Marvel Reddit recently, you have probably seen comments like: “Just watch Loki and No Way Home.” “You can skip Ms. Marvel and She-Hulk.” “They did not even include Secret Invasion.”
Secret Invasion had world-changing implications on paper, but very little of it has carried over into later projects so far. Meanwhile, She-Hulk, Ms. Marvel, Moon Knight, and Echo are generally considered lower-priority. Agents of S.H.I.E.L.D., the ABC series featuring several MCU characters, has approximately 90 hours of runtime and can be ignored if the focus is on understanding Doomsday.
The Most Important Show to Watch
If there is one project nearly every fan agrees belongs at the top of the homework list, it is Loki. The show basically becomes the owner’s manual for the multiverse, introducing the TVA, branching timelines, variants, and why reality now resembles a bowl of multiversal spaghetti. Then comes Spider-Man: No Way Home, because that is where Marvel tears open the multiverse and invites everyone from previous Spider-Man franchises to the party. Deadpool & Wolverine is another big one, thanks to its heavy TVA connections and the return of Fox-era Marvel characters.
