Captain America or Iron Man? Super hero registration or ungoverned capes? Pick a side, Marvel fans.

"Avengers: Age of Ultron" isn't even a week into its North American run and already fans are looking ahead towards next year's "Captain America: Civil War." That excitement was increased ten-fold by the release of promotional concept art that features Cap and Iron Man going toe-to-toe.

This summer's "Ant-Man" will bring Phase 2 of the Marvel Cinematic Universe to a close while "Civil War" will be the launching pad for Phase 3. In it, Tony Stark and Steve Rogers will stand on opposing sides of a philosophical issue. Stark believes that every superhero should be registered with the government (secret identity included) and have an autonomous entity to report to while Roger believes that a move such as that infringes on civil liberties. The disagreement will force many existing heroes to pick a side as lines are drawn and alliances are forged and broken.

"Captain America: Civil War" will be directed by Joe and Anthony Russo, who will also helm the two-part "Avengers: Infinity Wars."
