So many Hollywood actors desire to be included in the Marvel Cinematic Universe. Despite their youthfulness, Marvel has created some of the most well-known actors in the Marvel Cinematic Universe. However, existing actors have also played an essential role in the Marvel Cinematic Universe. Celebrity appearances in Marvel projects have either been planned for years prior to a release or have happened completely unexpectedly.
Some performances are off-screen, such as Miley Cyrus' voice in Guardians of the Galaxy Vol. 2, while others, like Harry Styles' Starfox, are planned to be key players in future Marvel films and series. Even anticipated appearances can add another layer of excitement to movies and series in a franchise with a large following.
Harry Styles 'The Eternals'
Harry Styles is no stranger to television guest appearances. He joined the Marvel Cinematic Universe as the brother of Thanos, Starfox, in a post-credits scene of The Eternals. Up to this point, Styles' acting career had been somewhat limited. For the most part, his only feature was Dunkirk.
Although social media spoiled the surprise that he appeared here, it was no less delightful. His almost elflike appearance lent itself perfectly to this otherworldly creature. This appearance played to Styles' unquestionable charisma.
Matt Damon 'Thor: Ragnarok'
Thor: Ragnarok was well-known for harnessing the Marvel Cinematic Universe's harrowing chaos. What only added to the chaos was a play depicting Thor: The Dark World's events. Enter Matt Damon and his motley crew of Asgardian players. This was a centuries-old parody.
This cameo was fantastic because of how it mocked the source material. This fragment of a play perfectly encapsulates Thor: The Dark World's melodrama. The fact that Matt Damon was leading the charge made this entire sequence even more hilarious. The part in Thor: Love and Thunder continued in the strongest possible way.
Melissa McCarthy, 'Thor: Love and Thunder'
Melissa McCarthy joined the Asgard Players in retaliating against the Asgardian aristocracy with humor.
McCarthy's surprise appearance made the Asgardian Players' entire concept more funny and ridiculous. This performance was a testament to McCarthy's ability to incorporate Marvel's trademark self-referential humor.
Kenneth Branagh 'Avengers: Infinity War'
Kenneth Branagh has accomplished everything in his long and distinguished career. Thor was directed by the multitalented Thespian, so he is no stranger to the Marvel Cinematic Universe. In Avengers: Infinity War, Branagh was the voice of the Asgardian distress call.
Branagh hasn't yet appeared on screen, even though he has made his directorial debut in the Marvel Cinematic Universe. Of course, his charisma makes him a natural choice to be the voice of such a crucial moment.
Howard the Duck 'Guardians of the Galaxy'
Howard the Duck has gained a bit of a cult following since the 1986 film Chaos. However, the character was given new life in the Marvel Cinematic Universe in the end credits scene of Guardians of the Galaxy.
This has become one of the most famous post-credit scenes in the Marvel Cinematic Universe. This was the time when it became clear that the MCU could do anything and bring any character from the comic canon into the franchise. It was so shocking that Marvel successfully re-introduced one of their weakest characters for this iconic moment.
Miley Cyrus 'Guardians of the Galaxy Vol.2'
Miley Cyrus, a former Disney star, is another popular figure who has had an MCU moment. She was the voice of Mainframe in Guardians of the Galaxy Vol. 2. This is the artificial intelligence embedded in the Ravager Clan's ship.
With the Disney-Marvel partnership, this cameo made perfect sense. Perhaps what made this appearance surprising was how natural and low-key it was. Cyrus is certainly a gifted artist. She made the most of every opportunity she had to make an impact.
Joan Rivers 'Iron Man 3'
Iron Man 3 was flooded with celebrity appearances, most of which criticized the film from within. Joan Rivers was a standout. She most criticized the renaming of War Machine to Iron Patriot. Her segment, The Fashion Police, was a platform to critique the suit's overall appearance.
Joan Rivers was one of the last people to be expected to take part in an MCU film, even briefly. She was from a different era, long before the Marvel Cinematic Universe cultivated a fandom. However, in true Joan Rivers fashion, she made her brief appearance go spectacularly.
Trevor Noah 'Black Panther'
Black Panther offered fans a fantasy world they'd all like to visit. Trevor Noah, a late-night comedian, lent his voice to the role of Griot in Everett Ross' (Martin Freeman) flight simulator.
Noah's hilarious performance in this film should not have been surprising. Even when you couldn't see him, his funny abilities were evident. The flight simulator sequences are among the most memorable in the film.
Charlie Cox 'Spider-Man: No Way Home'
Charlie Cox, who plays Daredevil, was always planning to return to the Marvel Cinematic Universe. This appearance in Spider-Man: No Way Home as Peter Parker's lawyer served as the official introduction of this character, who was featured in his own Netflix series.
Even though fans knew about this coming appearance, it was still quite shocking to see it unfold. This was a wonderful fan-service moment and a reminder of what made Matt Murdoch such a great character.
Megan Thee Stallion 'She-Hulk: Attorney at Law'
Jennifer Walters, in her Hulk form, is seen twerking with Megan Thee Stallion in She-Hulk: Attorney at Law season 1, episode 3. This is a joyous moment in a series that has made it a point to critique and ridicule popular culture.
Megan Thee Stallion, among She-Hulk's stacked cast of characters, should have come as no surprise considering what this program has attempted to accomplish.
