Many films and TV shows feature a large amount of star-studded Easter eggs and blink-and-you'll-miss-it moments, demonstrating how Marvel is always able to offer something new and unexpected every time.
These can include the likes of MCU behind-the-scenes staffers such as the Russo brothers, Jon Favreau, and James Gunn, as well as celebrities that have no involvement with the MCU and whose appearances provide comic relief. Here are a few of the most unexpected MCU cameos, minus the legendary Stan Lee.
Miley Cyrus - Guardians of the Galaxy Vol.2
The superstar singer and actress is only featured in a brief appearance in the second installment of the Guardians of the Galaxy franchise, as the Mainframe Ravager Clan's leader and during the funeral of Yondu Udonta's performance.
Miley only states one sentence: "I missed you guys so much," but it's no doubt that she's a nice surprise. Sylvester Stallone, Michelle Yeoh, and David Hasselhoff made the comeback. It's one of the most prominent MCU cameo films.
Matt Damon - Thor: Ragnarok
Thor: Ragnarok, a film directed by Taika Waititi, which is regarded by many to be the finest Thor film in the entire franchise, is made fairly early on in a play reenacting of Loki's "death," played by none other than Matt Damon.
The actor, who is most well-known for his role in the Bourne Identity franchise, was evidently unexpected in this MCU film, but he was nonetheless well-known for his performance, and he serves as one of the greatest comedy moments in an already funny film.
Luke Hemsworth - Thor: Ragnarok
Luke Hemsworth stars as Thor himself in the play-within-a-film that he directs. Hemsworth, who is Chris Hemsworth's real-life younger brother, makes one of the best MCU celebrity appearances ever and plays as a delightful tongue-in-cheek joke for the two brothers.
Both Matt and him, however, are unfortunately short-lived, even though fans would happily watch an entire retelling of the Thor franchise with Matt and Luke reprising their faux roles. Sam Neill also makes his appearance as "Odin" alongside the two, wearing makeup and golden Asgardian fashion to properly look the part.
Julia Louis-Dreyfus - Black Widow
Julia Louis-Dreyfus of Seinfeld and Veep fame takes on the role of Valentina Allegra de Fontaine in the post-credits scene.
Julia's participation sparked new questions about the new enemies and allies in the fourth phase of the MCU, and her energetic energy pushed fans to dream up her future roles in other films and shows.
J.K. Simmons - Spiderman: Far From Home
The issue of who would play the larger-than-life news mogul in Sam Raimi's Spider-Man trilogy was a hot topic after his legendary performance as J. Jonah Jameson. J.K. Simmons' portrayal would cast a huge shadow on anyone else who was brave enough to take the role.
Simmons was evidently thrilled to see him return to his previous role in Spiderman: Far From Home, which obviously fueled the excitement for the blockbuster film. He would then play a larger part in the latter, who has been rebranded as a parody of misinformation kings like Alex Jones, demonstrating a clear distinction between the news landscape of the early 2000s and today.
