"He makes an appearance in the next Avengers movie," Grillo said about his character. "But it's a flashback … I'm allowed to say whatever I want because I'm never doing another Marvel movie." (The reason why not, he revealed, had less to do with Rumlow's death and more to do with his age; "I'm 117 years old," he joked.)

Grillo's statement follows leaked photos from the Avengers 4 shoot that appeared to show Chris Evans in a version of the Captain America costume from 2012's The Avengers, standing in a set that resembles the New York setting of that movie, prompting fans to speculate about both a flashback sequence to happier, earlier times in the Marvel Cinematic Universe, or perhaps even a time-travel plotline. Now, it would appear to be confirmed that some of Avengers 4 will take place at some point prior to Civil War, although just when isn't clear yet.

Avengers 4 will be released May 3, 2019.
