A sensible Marvel fan would know to go prepared for the film that was already the continuation of several films in the Marvel Cinematic Universe.
Doctor Strange in the Multiverse of Madness was released on May 6 and has been well-received by the audience as well as the critics. The film is in a way a test of one's knowledge of the Marvel Universe with dozens of callbacks strewn throughout the film, that would keep a die-hard fan on their toes.
A sensible Marvel fan would know to go prepared for the film that was already the continuation of several films in the Marvel Cinematic Universe. With the multiverse being unleashed, there would definitely be a lot that would happen. They may have caught all the Easter Eggs in the film. Here are some of the mentions made in the movie that you may or may not have spotted:
The biggest references come from the animated series. If you thought the series was a fun spin-off that would have nothing to do with the rest of the MCU, you thought wrong. The most important reference comes from Strange Supreme who was mentioned in an episode. The giant tentacled monster called Shuma-Gorath, the mythical one-eyed, multiversal tentacle monster also made appearances in the film after first appearing in What If...? If you haven't already watched it, it would do good to revisit the series.
It was clear from the start that the events following the WandaVision series would be making their way to the Multiverse of Madness since Doctor Strange goes to her seeking guidance in the very first trailer. In the series, there is a mention of Mt. Wundagore in the post-credit scene. It is a part of the comics and in the film, Wanda is asked by Wong to travel there after her copy of the Darkhold is destroyed.
Sam Raimi directed the film and he is also known for his Evil Dead film franchise. References from his earlier movies made it into the Multiverse of Madness. Bruce Campbell who has played Ash in his films made a cameo in the film as Pizza Poppa who is bewitched by Doctor Strange to keep punching himself. He reappears in the end credits scene to break the fourth wall. Additionally, the iconic yellow Oldsmobile Delta 88 also has a cameo in the film.
America Chavez has the ability to travel the multiverse by punching open doorways. She is a lesbian in the comics and has two mothers. She is seen wearing her signature jacket and on it, she has accessorized it with a pride pin. This is a nod to her mothers as well as her own sexuality which is not discussed in the film. Her character was not well received in Saudi Arabia where they planned on banning the film because of America's sexuality. Much of the mention of her sexuality was censored for release.
I liked John Krasinski as Mr. Fantastic. He wasn’t given much to work with and I’m positive they’re saving the better costume design for his actual MCU counterpart. John can play the emotional beats that he needs to and he’ll be closer to feeling like comic Reed Richards. pic.twitter.com/dKFB8p8bHF— Block A 🌙 (@ChildOfKhonshu) May 11, 2022
Mister Fantastic, the leader of the Fantastic Four makes an appearance in the film. John Krasinski who plays Reed Richards shows up in the film as a foreshadowing of the new Fantastic Four film that is currently in development, irrespective of Reed's fate in the film.
Since the multiverse was opened, the different universes are numbered. Earth-616 and Earth-838 are mentioned in the film. Earth-616 is where all the main events of the MCU previously took place. On the other hand, various things have also happened on Earth-838 and happen in the film. This could mean that the intermingling between these two Earths has a lot set to happen.
Fantastic Four and Earth-838 have already been mentioned which means the mention of the Baxter Foundation in the film would be no surprise. It is an institution founded by Franklin Storm, aka Sue Storm's father. In the movie, it’s where Earth-838 Christine works and conducts research on the multiverse. This is yet again a nod to the Fantastic Four film that is coming.
The Illuminati is a secret organization from the comics and in the film includes Mordo, Peggy Carter, Blackagar Boltagon, Maria Rambeau, Reed Richards, and Charles Xavier on Earth-838. They had previously eliminated the danger of Steven Strange on Earth-616 after he defeated Thanos. We get to see a glimpse of X-Men's Professor X here as well as Peggy Carter as Captain Carter after she was injected with the super-soldier serum instead of Steve Rogers.
Maria Rambeau as Captain Marvel an alternate version of her character from Captain Marvel. In Earth-838, Captain Marvel is Carol Danvers’ close friend Maria Rambeau, played by Lashana Lynch. In Earth-616, Maria is dead, and her daughter, Captain Monica Rambeau, is a main character in the Disney Plus series WandaVision.
Perhaps it is a coincidence that the film was released on Mother's Day weekend since the film unfolds as the angry response of Wanda's motherly wrath.
