WARNING: SPOILERS! THIS IS ALL SPOILER-RELATED!
At the end of CAPTAIN AMERICA: CIVIL WAR, Sebastian Stan's Bucky Barnes, aka The Winter Soldier, was put on ice. The writers of that film seemingly wanted to remove Barnes from the current cinematic landscape until they could find an inventive use of the character again. That created the question: When will we see The Winter Soldier again?
According to The Hollywood Reporter: In about two years.
One of the industry's most trusted hard news outlets, THR made a passing reference to what Stan had coming up in terms of acting projects, and they mention what his next Marvel venture will be. So what is it? Since he was put into stasis while at T'Challa's headquarters, does that mean we'll see him in BLACK PANTHER? Nope. The site claims that good ol' Bucky is going to show up in AVENGERS: INFINITY WAR.
They claim the actor will start filming his fourth outing as Barnes in early 2017, and we know that the film is slated to come out May 4, 2018.
