1. Matt Damon
One of the most surprising cameos in the Marvel Cinematic Universe is that of Matt Damon in Thor: Ragnarok. Damon makes a brief yet memorable appearance as an Asgardian actor portraying Loki in a comical play organized by Thor’s mischievous brother.
This tongue-in-cheek role sees Damon donning a costume that mimics Loki’s iconic look, adding a layer of humor and surprise for audiences familiar with his serious roles in films like The Martian and Good Will Hunting. This scene, directed by Taika Waititi, perfectly encapsulates the film’s lighthearted tone while showcasing Damon’s versatility as an actor.
