If you’ve been around for the past decade (and now a little longer), there’s a good chance that you’ve seen the bulk of the movies in the Marvel Cinematic Universe. The MCU has had major stars play the main characters while also establishing new stars in the process. On top of it all, there have been some random cameo appearances from other celebrities, many of which didn’t even have a line. Here are some of the ones you might’ve missed.

Seth Green – Actor Seth Green has been around the industry for quite some time, most known for his work on “Family Guy” and “Robot Chicken”. In “Iron Man 2”, he had an extremely brief cameo. Green was shown as one of the attendees of the Stark Expo, and most fans missed it until the director pointed it out in the commentary. He also played the voice for Howard the Duck in a post-credits scene for “Guardians of the Galaxy”.

Rob Zombie and Miley Cyrus – For the second “Guardians of the Galaxy” movie, there were a couple of other celebrity cameos through voice only. Hard rocker Rob Zombie played the voice of the GPS system on the Ravagers’ ship, while pop singer Mily Cyrus voices Mainframe, a very minor A.I. character in the MCU.

Tom Morello – Music fans know Morello as one of the more popular guitarists of the past 30 years thanks to his hits with Rage Against the Machine and Audioslave. Morello was the first celebrity cameo, playing a guard in the first “Iron Man” film when Tony Stark is being held in a cave.

Chris O’Dowd – The actor, who has starred in shows like “Girls” and movies like “Bridesmaids” had a very brief appearance in “Thor: The Dark World”. In fact, his role was so overlooked that even O’Dowd forgot that he played Richard in the movie. “I forgot I was in that one before you just mentioned it,” he told a reporter. He didn’t even know the name of the film, guessing that it was “Thor-ier”.

“Community” Cast – Directors Anthony and Joe Russo worked on the cult classic comedy series “Community”, and used many of the directors in cameos. Danny Pudi played a security guard in “Captain America: The Winter Soldier”, Donald Glover had a memorable appearance as a criminal interacting with Spider-Man in “Homecoming” while Ken Jeong and Yvette Nicole Brown popped up in “Avengers: Endgame” as security guards.
