Overlooked MCU Details List
1. Lost Arms as a Tribute to Star Wars

If you’ve noticed that several Marvel characters seem to lose limbs in every other movie, it’s no coincidence. Kevin Feige, the president of Marvel Studios, is a huge fan of Star Wars and wanted to pay homage to the iconic space opera by incorporating some limb-chopping moments into the MCU.
As a result, characters like Thor, Aldrich Killian, and Bucky join the ranks of Anakin (and his later identity as Darth Vader), as well as Luke and Mace Windu, in experiencing limb loss throughout their stories.
2. Fake Infinity Gauntlet

Do you remember the fake Infinity Gauntlet in Thor: Ragnarok? It turns out it was actually a prop mistakenly designed as a right-handed gauntlet, rather than the true version meant for the left hand.
Additionally, Hela’s line in the film serves as a clever meta-reference to earlier films in the franchise. Pretty cool, right?
3. Vine Reference

Before TikTok took over, Vine videos were the internet’s big craze—and one of them was actually referenced in Black Panther! In a scene where T’Challa’s sister, Shuri, teases her big brother about his sandals, she dramatically asks, “What are thooooose?!” This line mimics the tone and delivery of a popular Vine that humorously mocked a police officer’s shoes.
4. Stan Lee

Fans have come to expect Stan Lee’s iconic cameos in every MCU movie, but some sharp-eyed viewers might have noticed him in the Marvel television series on Netflix as well. While he doesn’t physically appear in every episode, Lee’s face makes brief appearances in each Marvel Netflix series.
For instance, he can be spotted in Daredevil and Jessica Jones on a plaque displayed at the police station. Additionally, in The Defenders, there’s a poster of him in the background while Matt Murdock follows Jessica Jones.
5. The Return of Harley Keener

As most fans know, every character that appears in the MCU is significant, and their appearances are carefully planned, never by coincidence. This includes Harley Keener, who might be unfamiliar to some but is recognized as the boy who helped Tony Stark in Iron Man 3 after Stark’s house was destroyed while escaping Aldrich Killian’s men.
Harley also made a return in Avengers: Endgame, where he said his final goodbyes to Tony following his death.
6. Proud Flag

Black Panther was celebrated as a groundbreaking Marvel film that enhanced black representation worldwide. In the scene where T’Challa, Nakia, and Okoye enter the casino in Korea, the camera highlights the vibrant colors of their outfits, which reflect the pan-African flag.
7. Pulp Fiction Reference

Nick Fury is just one of Samuel L. Jackson’s iconic roles. After faking his death in Captain America: The Winter Soldier, the camera zooms in on Fury’s gravestone, which features a Bible quote from the book of Ezekiel: “The path of the righteous man…”
This serves as a nod to Quentin Tarantino’s film Pulp Fiction, where Jackson played Jules Winnfield, who quotes the same Bible verse during an interrogation scene.
8. The Right Stuff

The MCU is full of subtle details, and one of the more challenging ones to spot appears in Captain Marvel. After crash landing in a Blockbuster Video rental store, Carol Danvers picks up a videotape of the movie The Right Stuff.
Interestingly, this film takes place at Edwards Air Force Base, where Danvers was stationed before leaving Earth.
9. Farmer Thanos

After wiping out half the universe to restore balance, Thanos appears to have taken up farming. In the final scenes of Infinity War, he is seen overlooking a peaceful valley from his cabin. This mirrors the ending of the Infinity Gauntlet comic, where Thanos settles down as a farmer after the Avengers attempt to reverse his genocide.
10. The X-Men Jet

Although the X-Men were never explicitly included in the MCU, numerous references have linked the two over the years. The Scarlet Witch serves as one of the most significant clues, but these connections date back to Iron Man, when Tony Stark was testing his prototype suit’s altitude performance.
