The Marvel Cinematic Universe isn't just full of big stars now. Before Mark Ruffalo was stomping around as the Hulk and Lupita Nyong'o joined the fight in Wakanda, the Marvel movies were filled with celebrities.
Going back 10 years, there have been some pretty big cameos and appearances from actors you may have forgotten about or rising stars you missed entirely unless you did a recent movie binge ahead of the "Avengers: Infinity War" release.
INSIDER rounded up the actors you probably forgot appeared in Marvel movies over the past decade. We're looking specifically at the 19 Marvel Cinematic Universe movies that have been released. That does not include "X-Men" movies from Fox and Sony's "Spider-Man" saga.
Some of them are easier to remember than others. Sir Ben Kingsley played an odd villain in "Iron Man 3" and Don Cheadle famously replaced Terrence Howard as War Machine. Before Ruffalo was thrashing around as the Hulk, it was Edward Norton as the big green guy. Keep reading to see which stars appeared in the MCU.
