Avengers: Endgame will live up to its title, as the film will end the current era of the Marvel Cinematic Universe as we know it, and likely a few central character arcs as well.

Behind the scenes, Marvel Studios will see some of its most prominent stars fulfill their Marvel Cinematic Universe contracts in full when Avengers: Endgame comes out, and the biggest loss fans expect is none other than Robert Downey Jr.'s Tony Stark/Iron Man. We've known for some time that Downey is but one big MCU contract ending with Avengers: Endgame, as Captain America actor Chris Evans previously revealed that he, Downey, and Chris Hemsworth are all contractually done as of this fourth Avengers movie:

“Myself, Downey, Hemsworth, we all kind of started roughly at the same time, and I think we all, through Avengers 4, kind of wrap it up,” Evans said. “So at this point, I don’t know what’s next, but yeah, by 2019, that’s it.”
