Captain America: The First Avenger and Captain America: The Winter Soldier writers Christopher Markus and Stephen McFeely are currently working on the script for Captain America 3, which now has its May 6, 2016 release date all to itself, after Warner Bros. moved their highly-anticipated sequel Batman v Superman: Dawn of Justice to March 2016.

While the writers wouldn't divulge any plot specifics for the sequel in a new interview with SFX, Christopher Markus teased that he would like to bring MODOK into the Marvel Cinematic Universe, at some point. Here's what he had to say, when asked if there were any classic comic book characters they couldn't quite fit in to Captain America: The Winter Soldier.

"I don't know if there's anybody that we had in the wings that we couldn't pull off. 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...' [laughs]. Suddenly the whole movie needs to take on that structure in order to accommodate him. I never win that fight!"

Back in 2011, just a few months after Captain America: The First Avenger debuted, Christopher Markus revealed that he wanted MODOK to be the main villain in Captain America: The Winter Soldier, and that he wanted Peter Dinklage to play him. Obviously, that didn't happen, but perhaps we'll see MODOK in Captain America 3?

In the Marvel Comics, MODOK was one of Captain America's primary adversaries during the 1960s, who used to be a human technician for Advanced Idea Mechanics (AIM) named George Tarleton. The AIM scientists used advanced mutagenetics to transform George into MODOC (Mental Organism Designed Only for Computing), although he soon killed off the scientists and became MODOK (Mental Organism Designed Only for Killing).

When asked about the tone of Captain America 3, Christopher Markus says that it will be a cross between the first two movies.

"Well, that's the challenge! But we are working on something that I think is an amalgalm."

Stephen McFeely also elaborated on the sequel's tone.

"When we hit upon the 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!"

Christopher Markus revealed that another one of the Avengers was due to make a cameo in earlier drafts of the Captain America: The Winter Soldier script, but it never came to fruition.

"There were actually drafts where we had Hawkeye in it, but he didn't have enough to do and suddenly it seemed like we were giving him short shrift. Hey, it's a cameo!"
