We know that Captain America: The First Avenger, which takes place during World War II, will be book-ended by contemporary scenes leading into next summer's epic superhero ensemble The Avengers. While that adventure will take place in today's timeline, it's possible that Steve Rogers (Chris Evans) will eventually head back to the comic's original 1940s landscape for Captain America 2.

Screenwriters Christopher Markus and Stephen McFeely recently chatted about potental story ideas for Captain America 2, and the timeline within which it would occur. This is what Christopher Markus had to say.

"We're very early, still. This is the fun part - when we can say, "Hey, we can do this!" and everyone says, "Yeah!" No one says anything negative at this point in the process. We have a million great ideas and haven't thrown any of them out yet. That being said, it's sort of a weirdly huge opportunity for storytelling in that you know modern Cap through the The Avengers at that point, and just by the nature of what we were talking about before, there's going to be a lot of his World War II history we haven't shown. We're going to have two entire timelines to play with."

Stephen McFeely continued by adding this.

"I wonder if the reaction to Captain America: The First Avenger will steer us in some way. First, if it does well... Then, if it does well and people embrace the World War II aspect of it, maybe there's pressure to return there in a large way. But if they don't embrace that aspect and just love Chris Evans as Steve, maybe there's less pressure to do that - you can just keep him in The Avengers universe."
