Marvel’s much-anticipated Captain America: The Winter Soldier opens in just about two weeks, but there has already been some news about that film’s eventual follow-up. Recently, it was revealed that Captain America 3 would be opening on May 6, 2016 (the same day as WB’s Man of Steel sequel). We know that Joe and Anthony Russo will return for the third film, and that they’re currently breaking the story with returning screenwriters Christopher Markus and Stephen McFeely. While promoting the upcoming film, the screenwriters may have let slip the comics source for the framework of the plot of the next installment. Hit the jump to get a little crazy.

In an interview with Den of Geek (via BC), Markus and McFeely grudgingly shared this little plot nugget for Captain America 3:

Are you going back to the comics for the next one and plan to adapt another story, while incorporating the many threads left open at the end of this one?

McFeely: Oh yeah, you can probably predict some of the threads we would like to pick up again that we’ve laid out there. And we always go back to the comics and dive back in and look at anything we’ve missed in the last few years that might be relevant.

Markus: We’ve definitely set out on a more realistic road in the Cap movies, you know. Even more grounded than in the other MCU movies. And so it kind of rules out Cap fighting the Dinosaur Man or something like that. There are some that aren’t gonna start and other ones that — I mean there’s a couple we’re playing with right now that we really want to take elements from. Which we’ll not reveal.

Oh, come on.

Markus: All I’m saying is psychotic 1950s Cap.

Amy Acker is gonna be on Agents of SHIELD!!!! She'll play the cellist Coulson was dating in The Avengers, and is being menaced by a super-powered threat from her past. I'm pretty excited and might even watch this episode because Acker is an absolutely phenomenal actress (and has made frequent appearances in Whedon projects, like Angel, Dollhouse, Cabin in the Woods, and Much Ado About Nothing).

Now, what would be perfect is if Deathlok randomly showed up in one of her scenes so we could get an Angel reuinon!

Alright you dumb, unpatriotic jerks, going around trying to spoil AN AMERICAN MOVIE that hasn't even COME OUT IN AMERICA YET;

    Gunn freezes a frame of an imposing-looking villain any serious comic book fan would recognize instantly. He sits on a rocket-powered throne. Feige sees something on the screen that he doesn't like. The evildoer needs to be farther away in the frame so he looks more imperious, he says.

    "I don't know," says Gunn. "I think it's going to look cool, man."

    "You just don't want him to feel petty in that way," Feige says. "I think it's a fine line."

    "How do you think it comes off as petty here?" Gunn says.

    "He's so damn close," Feige says.

    "Yeah," concedes Gunn. "I think I'm going to have him floating in space."

    Feige is concerned about the throne, too. He points at the base. "Those don't need to be rockets," he says. "Maybe gravity disks?" Feige says he'll check back later.

    In the hallway he extracts a pledge not to name the bad guy. "That could not be a bigger spoiler," Feige says.
