After its official release, "Doctor Strange in the Multiverse of Madness" received quite polarized reviews globally. However, there's no doubt that this film is Marvel's most ambitious milestone to date, truly unlocking infinite possibilities for the MCU multiverse. Below, we've compiled 36 Easter eggs and details from "Doctor Strange 2" for you!
1. Opening Credits
If you look closely at the Marvel logo animation in the opening credits this time, you'll notice a few extra snippets from Doctor Strange's past, as well as Wanda's transformation into the Scarlet Witch from "WandaVision."
2. The Book of Vishanti
America Chavez and Supreme Doctor Strange are fleeing from multiverse monsters, with their goal being to obtain the Book of Vishanti.
In the comics, the "Vishanti" are a trinity of celestial beings composed of Oshtur, Hoggoth, and Agamotto.
In the MCU, the "Vishanti" first appeared in the "What If...?" series.
3. America Chavez
This film also marks the MCU debut of "America Chavez," a Latina girl born with the ability to travel through the multiverse. Upon her first appearance, she converses with "Supreme Doctor Strange" in Spanish.
America's jacket features a rainbow pride flag on the chest pocket, and the zipper edge is inscribed with "Amor Es Amor" (Love is Love) in Spanish, honoring America Chavez's LGBTQ+ identity in the comics.
In the comics, America's girlfriend is Lisa Halloran, an emergency medical technician. However, America's most well-known partner is her best friend, the new "Hawkeye," Kate Bishop. While not officially dating, their relationship is more than just friendship.
4. A Sorcerer's Daily Life
Strange uses magic for small daily tasks, such as tying his tie remotely and refilling Christine's drink at the wedding. The same technique also appeared in "Thor: Ragnarok."
5. Garganto Battle
The monster that causes chaos in the streets of New York when America is transported to the MCU universe in the opening scene is named Garganto, according to toys. However, in the comics, it should be Shuma-Gorath. Due to potential copyright issues, as the name comes from Cthulhu Mythos novels, it was changed to Gargantos, a minor villain from the "Namor" comics with a similar shape.
This sequence also features several distinctive touches, such as viewing Strange's transformation into a superhero and his battle through the eyes of Christine and wedding guests. It also contains one of Marvel's most bloody and violent scenes to date, where Doctor Strange impales Garganto's eye with a lamppost and pulls it out. This is, of course, a touch from Sam Raimi. The New York street aesthetic here is also consistent with Sam Raimi's "Spider-Man."
6. Spider-Man
Doctor Strange and Wong take America Chavez to a pizza parlor to discuss the multiverse. Doctor Strange mentions some things about Spider-Man, referring to the events of "Spider-Man: No Way Home." However, because the spell made everyone in the world forget Peter Parker, both Doctor Strange and Wong claim not to know what Spider-Man looks like.
Incidentally, this film was originally planned to be released before "Spider-Man: No Way Home," and there were plans for America Chavez to debut in this film and then assist the three generations of Spider-Men in their battle in "No Way Home."
7. WandaVision Theme Song
When Doctor Strange thinks of seeking Wanda's help, the theme melody from the "WandaVision" series plays, and we see Wanda living happily with her twin children, Billy and Tommy. Of course, this is all just a dream.
8. The Darkhold
In the post-credits scene of "WandaVision," Wanda's encounter with Agatha's "Darkhold" triggers her transformation into the Scarlet Witch, and she becomes corrupted by it, threatening Strange to hand over America. The "Darkhold" is a grimoire of dark magic written by the Elder God Chthon, who dedicated his life to studying forbidden dark magic and compiled its spells into the "Darkhold."
The version in the film first appeared in the "WandaVision" series, but another version had already appeared in "Agents of S.H.I.E.L.D.," produced by Marvel Television. Official answers are currently inconsistent, but in the comics, the cover of the "Darkhold" can change, so it remains to be seen if Marvel Studios will acknowledge the story of "Agents of S.H.I.E.L.D."
9. Savage Land
When Doctor Strange and America Chavez fall through the multiverse, one of the universes is filled with dinosaurs. In the comics, there is a pocket dimension located in Antarctica called the "Savage Land," the only place on Earth where dinosaurs still exist.
10. Living Tribunal
In one of the universes, several heads can be seen. Sharp-eyed comic fans will immediately recognize them as the "Living Tribunal." In the comics, they are the supreme judges who manage and balance all realities in the multiverse. They previously appeared in stone sculpture form in the "Void" at the TVA in the "Loki" finale.
In "Doctor Strange 1," Mordo once introduced a magical artifact called the "Staff of the Living Tribunal":
11. Bruce Campbell
The two eventually arrive in a technologically advanced city where traffic rules are reversed from reality. A street vendor selling pizza balls is a cameo by Bruce Campbell, Sam Raimi's long-time collaborator. Bruce Campbell has made cameos in many of Sam Raimi's works; in the Tobey Maguire "Spider-Man" trilogy, he played a boxing announcer, a restaurant owner, and other roles.
Doctor Strange uses magic to make the pizza ball vendor punch himself in the face, a homage to a classic scene from the 1987 horror film "Evil Dead," directed by Sam Raimi and starring Bruce Campbell.
13. America's Origin
This film reveals that America has had the ability to open the multiverse due to fright since childhood, which inadvertently caused her two mothers to be sucked into the multiverse. However, in the comics, her parents willingly sacrificed themselves to save the universe, becoming one with it. Strange believes her parents might still exist, laying the groundwork for a plot similar to finding the original Wasp in "Ant-Man and the Wasp."
14. Sands of Nisanti
Mordo from Universe 838 pretends to confide in Strange but secretly adds Sands of Nisanti to his tea, causing him and America to fall unconscious. In the comics, this artifact is contained in an hourglass and can suppress any form of magic within three minutes. 
15. Oswald the Lucky Rabbit
When Wanda travels to her home in Universe 838, Tommy and Billy are watching Disney's earliest black-and-white cartoon, "Oswald the Lucky Rabbit." This mascot was the predecessor to Mickey Mouse, but due to a copyright loophole, he was forcibly sold to Universal, leading Walt Disney to create the household name Mickey Mouse. It wasn't until 2006 that Oswald the Lucky Rabbit returned to Disney's hands and was set up as Mickey Mouse's older brother.
Wong reveals that the true "Darkhold" is located on Mount Wundagore. In the comics, Mount Wundagore is the fortress of the "High Evolutionary" and Wanda's birthplace. Wanda was blessed by Chthon there at birth and received guidance from the witch "Agatha," gradually becoming the "Scarlet Witch."
17. Baxter Foundation
Christine from Universe 838 states that she works for the "Baxter Foundation," an organization derived from the 2015 "Fantastic Four" (Fan4stic) movie. In the comics, it's the "Baxter Building" founded by "Mister Fantastic."
18. Universe Numbering
Christine explains that their organization is responsible for studying and numbering the multiverses, and our familiar MCU prime universe is designated 616, which corresponds to the prime universe numbering in the original comics. This has been mentioned previously in "Spider-Man: Far From Home" and the "Loki" series.
Previously, Marvel considered the comic and cinematic worlds as part of the same multiverse, so the MCU's official designation was EARTH-199999. However, in recent years, as the MCU has expanded its multiverse, the comic and cinematic universes have been separated, with 616 now serving as the prime universe designation for the MCU.
19. Captain Marvel
The Illuminati's "Captain Marvel" is Maria Rambeau, replacing Carol Danvers from the prime universe, with Lashana Lynch returning to reprise the role.
20. Captain Carter
Hayley Atwell returns as "Captain Carter," who first appeared in the "What If...?" series. She became a super-soldier after Steve Rogers was unexpectedly attacked while receiving the serum, taking his place.
21. Black Bolt
Anson Mount returns to star as "Black Bolt," king of the Inhumans, marking another return of a Marvel Television series member after "Daredevil" and "Kingpin." His design is also more faithful to the comic book depiction, with a device on his forehead that controls his supersonic vocal abilities.

22. Mister Fantastic
The MCU version of "Mister Fantastic" is played by "A Quiet Place" actor John Krasinski. Krasinski was already a popular fan-cast choice for "Mister Fantastic" long before discussions with Marvel in 2020, with many fan-made artworks circulating online.
Additionally, "Mister Fantastic" makes his appearance through a holographic portal, which originates from "Doctor Doom's" time-traveling portal in the comics.
23. 60s Chart Toppers
Strange hears the name "Fantastic Four" and mistakenly thinks it's a popular music group from the 60s chart toppers. This is a nod to 1961, the year the "Fantastic Four" comics first debuted.
24. Professor X
When Patrick Stewart returns as "Professor X," he can be seen in his classic "Hoverchair" yellow wheelchair. Simultaneously, the opening theme melody of the "X-Men" animated series (formerly known as "X-Men: The Animated Series") plays:
This classic Hoverchair yellow wheelchair was also immortalized as a figure and vehicle set in the Hasbro Marvel Legends series, highlighting its iconic status.
25. Battle of Titan
"Professor X" shows Strange the true cause of death for Universe 838's Strange: he recklessly used the dark magic of the "Darkhold" to defeat Thanos, leading to an incursion, and was executed on Titan. In this scene, Thanos can also be seen in the corner of the frame, impaled and dead.
26. Incursion
Additionally, the concept of incursions first appeared in the 2012 "Marvel NOW!" comics. After the "Age of Ultron" storyline, Wolverine repeatedly rewrote the timeline, causing incursions. The most famous instance is in the "Secret Wars" comics, where multiple universes collided, ultimately leaving only the 616 prime universe and the 1610 Ultimate Universe surviving.
27. "Days of Future Past" Quote
Professor X trusts 616 Universe's Strange, saying, "Just because someone stumbles and loses their way doesn't mean they're lost forever." This line is directly taken from his advice to his younger self when he traveled back in time in "X-Men: Days of Future Past."
When Wanda attacks the Illuminati headquarters, "Mister Fantastic" tries to reason with her, mentioning that he also has a wife and children, referring to "Invisible Woman" and their two children, Franklin and Valeria.
It's worth noting that the most popular fan-cast actress for "Invisible Woman" is Emily Blunt, who is Krasinski's wife; Emily Blunt was also once an official candidate for "Black Widow."
29. I can do it all day
During her confrontation with Wanda, Captain Carter utters Steve Rogers' classic line: "I can do this all day."
Captain Carter is ultimately cut in half through the abdomen with her own shield, mirroring how Zombie Captain America was killed by Bucky in "What If...?"
In the Dark Doctor Strange universe, 616 Strange mentions his sister Donna, who died in a glacier accident. In the comics, Donna Strange drowned in an accident.
He also had a younger brother named Victor. Stephen argued with him at home after their father fell ill, and Victor, in a fit of anger, ran out of the house and was accidentally hit by a car and died. He was later resurrected by the power of the "Darkhold" but became corrupted and turned into a vampire.
32. Third Eye
Doctor Strange develops a "third eye" due to his use of the Darkhold. In the comics, the "third eye" is the true form of the Eye of Agamotto. The third eye allows him to see the truth and souls of all things.
In the opening battle with Garganto, Garganto was initially invisible. Everyone only saw buses and the surroundings being violently destroyed by an unseen force until Strange used the Eye of Agamotto (proving he still has its inherent abilities even after the Time Stone was removed) to reveal Garganto's true form.
