In the Marvel films, there's only one Captain America, and his name is Steve Rogers.

In other words, despite rumors to the contrary, the upcoming Winter Soldier sequel won't feature William Burnside — the psychopath best known for running around in Cap's star-spangled costume in the 1950s.

But you could be forgiven for thinking Burnside would appear in the untitled Captain America 3, considering that writers Stephen McFeely and Christopher Markus previously tossed out an explicit mention of the "psychotic 1950s Cap." But in an interview with ComicBookMovie.com, the writing team backpedaled on their earlier remarks, putting out the Internet fire they effectively started.

"That was a smart remark, off the cuff," Markus said. "What I love about that whole run, the whole existence of that, is the sort of single minded desire to retcon everything into continuity, you know? 'But there was five issues in 1950 where he was a jerk!' I know he was a crazed college professor who had plastic surgery, but I think we can honestly say that he will not be making an appearance."

Then again, maybe the writers aren't ready to completely crush that particular rumor, as McFeely added: "You know, there's probably 20 minutes of movie there. There's something interesting about a guy who so desperately want to be [Captain America] and be a tribute...I just don't think it's a whole movie."

We'll know about Burnside with 100% certainty, one way or the other, when Captain America 3 slings its shield into theaters on May 6, 2016.
