Just like CA:CW really wasn't anything like the comics, CWII wouldnt have to be either. Also probably wouldn't need to be a "Captain America" movie. But at some point would you like to see another Civil War movie 5, 10 or 20 years from now? In CA:CW we saw a total of about 12 heroes (two teams of six) going at it. By the time Infinity War rolls around we will have a plethora of heroes who weren't apart of the Civil War that would also have opinions about the Accords and various methodologies when it comes to saving the planet. Including but not limited to: Doctor Strange Ms Marvel Daredevil Luke Cage Jessica Jones Iron Fist Punisher Wasp Not to mention Hulk, Thor, and Guardians of the Galaxy. So would you like to see more Civil War action again on screen in the future?
