With the release of Captain America: The Winter Soldier on DVD and Blu-ray, screenwriters Christopher Markus and Stephen McFeely talked the sequel and what possible new faces would pop up in the third movie.

'Captain America 3': Steve/Bucky Relationship To Be Central To Story

Speaking with SFX on Wednesday, the duo talked about crafting the political thriller within Winter Soldier and how it was a great segue into showing Steve Rogers the changes in the world.

"I know at some point Kevin Feige suggested "Well, why don't we just take down SHIELD? And have Cap have a hand in it?" He's one man versus this giant organization - you're not going to have him drive in with a tank so there's going to be some underhandedness. And suddenly it begins to suggest a political conspiracy," Markus said.

"If you put that 1940s man into present day geo-politics everything is going to seem like a conspiracy. It's just going to seem dirty and underhanded and shifty, and people won't be telling the truth. I have a tendency to believe that it was exactly the same way in 1945 but it's not how we view it. It becomes a political conspiracy simply by putting 1945 Steve Rogers in present day America."

As for future Captain America characters that could show up in the movie, Markus was very keen on getting a specific villain into the plot.

"There are people that I'm always wanting to bring in. I want to put Modok into something, but you can't just drop a giant floating head in! It's not like 'Oh, we have to go talk to this guy - there's something I should tell you about him first...,' Markus said.

"Suddenly the whole movie needs to take on that structure in order to accommodate him. I never win that fight!"

The writers also addressed the comic book switch to Sam Wilson as Captain America and whether that change would happen soon in the movies. "We tend to stay on the sidelines when it comes to the comics. We wait and see what we'll steal from in three or four years from now," McFeely said.

"I think the movies can accommodate almost anything, if there's a need. I think there is a much greater need to shake things up in the comics because that's a narrative that's been going on for 60 or 70 years, so you're going to wind up having to do things to it," Markus said.

"Ours has only been off the ground for five or so. So it's not quite time to start changing things up yet."

Captain America 3 opens in theaters on May 6, 2016.
