Many of the MCU movies and shows can be enjoyed without having seen any of the other MCU movies or shows. However, most of them are improved with some context gleamed from the other stories. Therefore, I would like to suggest which shows I think you should try and watch before going to see Doctor Strange in the Multiverse of Madness, if you have time.
Doctor Strange 2 is out on May 2. I am writing this in April. These are only predictions for what films and shows will be relevant to best enjoy the new Doctor Strange movie, based on having seen pretty much everything in the MCU myself.
This list is in release order:
Doctor Strange: It is very likely Multiverse of Madness will assume you have watched the movie that introduces Doctor Strange. If you watch the sequel first I’m confident you’ll be able to pick up the key points, but it’s still a good idea to have an introduction to the characters. Likelihood of being important: 4/5
Avengers: Infinity War/Endgame: Characters from Doctor Strange had major roles in the two Thanos movies, but more than this, a large number of the stories released after Endgame have referred to the events of these movies in some way. Putting this on the list opens a can of worms, because if you want to watch Infinity War you really should really watch some of the other films first, but that’s just how the MCU is now. It’s only a guess that this will be relevant, though. Likelihood of being important: 2/5
WandaVision: This seems to be the story that directly precedes Multiverse of Madness. Wanda is featured heavily in all the marketing materials for the new film, and WandaVision tells you how she got there. Likelihood of being important: 5/5
Loki: This films dives heavily into the multiverse aspect of the MCU. I don’t think there were any direct indications that Doctor Strange 2 will pick up threads from Loki, but it’s very easy to guess that it will, just based onthe fact that both stories centre around the multiverse, and Loki did leave some big ol’ threads lying around. It’s totally possible they won’t be touched until Loki Season 2, though, so this one is just a guess. Likelihood of being important: 2/5
Spider-Man: No Way Home: It was the last movie released inthe MCU and Doctor Strange had a starring role. The plot revolved around the multiverse. I would be surprised if this wasn’t referenced in some way. As with the Avengers movies mentioned above, you probably don’t want to watch this without seeing some of the other Spider-Man movies. Likelihood of being important: 3/5
Summary
What films do you need to watch before Doctor Strange 2?
The films most likely to have significance to the plot of Doctor Strange in the Multiverse of Madness are the original Doctor Strange movie (for introducing the characters and rules of magic in the MCU) and WandaVision (as the direct prequel from Wanda’s perspective, and for introducing ideas that will likely make a return in this movie). Endgame and Loki could be significant as well.
