Variety is reporting that Captain America 3 will co-star Robert Downey Jr. as the cinematic universe attempts to bring to life the Civil War storyline that pitted Cap against Tony Stark.
According to Wikipedia, “The plot of the series follows a framework storyline in which the U.S. government passes a Superhero Registration Act ostensibly designed to have superpowered 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.” Tony Stark was in favor of the Superhero Registration Act while Cap was against it.
The report also includes details about the negotiations with Downey Jr to have him join the project.
Marvel did not comment on the report.
