Updated April 24, 2018: Chris Evans is still playing coy about his future as Captain America following Avengers: Infinity War and its untitled sequel - saying its "tough to say" whether he'll return as Steve Rogers.
“Part of you almost kind of thinks: Well, if we end on the right note… and I think it really kind of does. The scripts they have are really beautiful and really well-written. They do such a good job," Evans told Variety. "It’s really sweet and lovely and just special, and everyone really has a nice tight plot and story arc. Part of you almost doesn’t want to mess that up. … I guess it depends. It’s hard to know where your head’s gonna be at in a few years.”
That doesn't necessarily contradict Evans' previous statement of having "no plans" to return in the role, though now it seems he's already considering what the future may hold.
Original Story: Chris Evans has kept his future as Captain America ambiguous in the lead up to Avengers: Infinity War, but in a new interview with the New York Times, he seems to confirm his retirement from the role following Avengers 4.
“You want to get off the train before they push you off,” Evans told the Times, who elaborated that the actor's Marvel Studios contract will be up following Avengers 4, and said the actor has "no plans to return" as Captain America.
Evans' next appearance as the character is in April 27's Avengers: Infinity War. The still untitled Avengers 4 is scheduled for a May 3, 2019 theatrical release.
