Evans posted that he had completed work on the fourth Avengers film, and he announced it with this rather sentimental message:
Evans' first appearance as Captain America came in 2011's Captain America: The First Avenger. Since then, he has appeared in all three Avengers movies (plus the upcoming fourth film, slated for 2019). He's been the star of all three stand-alone Captain America films.
Officially wrapped on Avengers 4. It was an emotional day to say the least. Playing this role over the last 8 years has been an honor. To everyone in front of the camera, behind the camera, and in the audience, thank you for the memories! Eternally grateful.— Chris Evans (@ChrisEvans) October 4, 2018
Evans suggested earlier this year that he would stop playing Captain America after the forthcoming Avengers film. He new tweet seemingly confirms that.
