Screenwriters Christopher Markus and Stephen McFeely dropped some major spoilers about the third Captain America movie.

In an interview with a website SFX, the writer teased about what to expect in the movie and a few characters that are unlikely to make the final cut.

McFeely told SFX: "When we hit upon the Ed Brubaker run of the comic book, we all said that, with certain exceptions, that's the tone of Cap's modern franchise.

"And you can imagine that with us back, with the Russos back, then if you like Winter Soldier you'll hopefully like the third one, if we do it right!"

Ed Brubaker handled the series from 2006 to 2012 and co-created the Winter Soldier character.

The third movie would be "an amalgam" of the first two in terms of tone, but Christopher Markus warned fans not to expect the movie to follow the current direction of the comics where Falcon replaces Steve Rogers as Captain America.

"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," he said.

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

McFeely joked that he will "wait and see what we'll steal from in three or four years from now" when it comes to comic book storylines.

Markus also teased about a Modok movie!

"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," he explained.

"I never win that fight. Even so, it's worth keeping up the good fight. If Groot can be a thing, then the world is definitely ready for Modok: The Movie."

Captain America 3 is scheduled for a May 2016 release.
