His appearances have ranged from drinking a bottle of poisoned soda in The Incredible Hulk to being a FedEx driver in Captain America: Civil War.
He’s also graced a few Marvel TV shows, too, like Agents of S.H.I.E.L.D. and Agent Carter.
He most recently appeared in Guardians of the Galaxy Vol. 2 as an informant for The Watchers, and it was there that it was confirmed that he’s been playing the same character in all the MCU movies.
While Stan Lee has missed a few Marvel movies over the years, like several X-Men entries, for the most part we can count on him to show up for a few seconds in any feature film that hails from the House of Ideas, even if it’s a movie starring characters he didn’t have a hand in creating.
