Word on the street is that Robin Downey Jr is close to signing on for Captain America 3. Looking at the current Marvel movie structure it would seem that a Civil War could be on the cards.
Written by Mark Millar and pencilled by Steve McNiven, Civil War was its own limited title which also ran through various other titles published by Marvel at the time. The storyline builds upon the events that developed in previous Marvel crossovers, particularly “Avengers Disassembled“, “House of M“, “Decimation“, and “Silent War“. The tagline for the series is “Whose Side Are You On?”
The plot of the series follows a framework storyline in which the U.S. government passes a Superhero Registration Act ostensibly designed to have super powered characters act under official regulation, somewhat akin to police officers. The events of the series touch upon themes of liberty, moral responsibility, and civil order, with good-intentioned superhero characters finding themselves upon different sides.
