While "The Avengers: Age of Ultron" is still in the theaters, fans cannot help but observe the difference in opinion between Captain America and Iron Man in the movie. Marvel fans know where that is heading—"Civil War."

But aside from the showdown between the two Avengers, Marvel has come up with a way to spice things up a bit. Marvel has inked a deal to get Spider-Man on board "Civil War" so it looks like that the webslinger might just actually make the third "Captain America" movie.

Iron Man himself, Robert Downey Jr. had a chat with David Letterman where he was asked about Spidey being in the movie. Downey confirmed it by saying "He may well be, yeah. I hear they're looking to cast a new Spider-Man."

If this is really true, "Captain America 3" will be an all-star superhero cast including Black Widow, Hawkeye, The Vision, Ant-Man, Scarlet Witch, War Machine, Black Panther, Falcon and Winter Soldier. That is surely one way to go out as rumors point to "Civil War" being the movie where Steve Rogers will die.

Elsewhere, Daniel Brühl finally confirmed his role in the movie. While there have been write-ups about Bruhl's casting and what role he will play, only the actor himself can confirm it.

"I think I can tell you that without being thrown into Marvel prison. For the first few days I'll walk around like a little boy, just amazed by the megalomania of it. It's such a huge project. We could do 20 films with the budget," Brühl told The Independent.

Baron Zemo is a Nazi scientist who wants to avenge his father, Heinrich Zemo's death. He will play a villain in this movie as well as Crossbones (Frank Grillo) and Winter Soldier (Sebastian Stan).

It looks like Steve Rogers will have a lot on his hands come May 6, 2016 when "Captain America: Civil War" hits the theaters.
