WARNING: Potentially MAJOR SPOILERS ahead for Thor: Ragnarok!
While Stan Lee is the undisputed cameo king of the Marvel Cinematic Universe, the franchise has recruited a number of actors over the years to make quick appearances. For instance, the late and great Harry Dean Stanton popped up in The Avengers as a security guard who witnessed The Hulk crashing from the sky and transforming back into Bruce Banner. Well, Thor: Ragnarok is next up on the MCU slate, and if a new rumor is to be believed, then moviegoers will be treated to Matt Damon gracing the screen as an Asgardian performer.
