What to Watch Before Avengers: Doomsday
The new Marvel Studios film, releasing December 18, 2026. Six months. Forty-plus films. A few reasonable paths. Marvel.com · IMDb
You have six months. The MCU has more than 40 films and shows. You cannot watch all of them. You also do not need to.
This is the prep manual for getting yourself ready to walk into a theater on December 18, 2026, and actually enjoy the biggest Marvel film since Endgame, without giving up sleep, your social life, or the part of your brain that remembers what your job is.
You will not need a flashlight, canned goods, or a go-bag for this one. You will need a streaming subscription, about 31 hours of free time spread across six months, and a willingness to skip some films a lot of people insist are required.
This guide tells you which ones.
Yes, the prep-manual language is mostly a joke. Doomsday is a movie, not an actual emergency.
But the underlying problem this guide solves is real. People who want to enjoy Doomsday in December are getting buried under "you have to watch all 40 films first" advice that is wrong, exhausting, and gatekeeps a universe that is supposed to be fun. This manual is the antidote to that.
The films and shows we are protecting are silly, beautiful, sometimes profound, and almost always entertaining. The prep is about clearing your runway so you can actually enjoy them, not about treating any of this like a military operation.
If anything in this guide stops being fun, you are reading it wrong.
- The person who has not watched any Marvel and wants to start
- The person who watched some Marvel years ago and lost the thread
- The person who watched most of it but cannot remember what happened in The Marvels
- The person whose friends are dragging them to Doomsday in December and who wants to actually understand what is happening
- Anyone with finite time and infinite homework
This is not for the person who has seen every film, watched every show, listened to every podcast, and memorized every post-credits scene. Those people do not need this manual. Send it to a friend who does.
