Avengers: Infinity War - 10 Things That Must Happen In Part 1

8. Captain America & Iron Man Must Put Their Differences Aside

Captain America: Civil War is to be one of the biggest Marvel Cinematic Universe entries to date, given that it features an endlessly exciting plot that pits fellow Avenger Steve Rogers against Tony Stark after the government orders a superhero registration act to regulate and oversee activity. If you've read the comics on which said movie is based, you'll know that this act results in a huge and dangerous divide between all the major superheroes - new alliances and rivalries are formed, and things get really, really messy. But whatever happens, and however the events in Civil War are left to fester come time for the credits to roll, Captain America and Tony Stark will have to put their differences aside in order to take on an even bigger threat: that of Thanos, and his plan to enslave the entire galaxy. Expect the boys to kiss and make up in a begrudging scene.
