Avengers Endgame or Assemble? Inside wild fan theories sparked by Russo brothers' cryptic photo

It's been a good year for Marvel fans. With blockbusters like 'Black Panther', 'Avenger: Infinity War', and 'Ant-Man and the Wasp' setting a pretty good record at the box-office, all eyes are now on the upcoming spate of movies, which not only will define the fate of Earth's mightiest heroes but also will mark the end of Phase III in the Marvel Cinematic Universe.
Beginning of the next year, though, superhero movie lovers would be gearing up for two back-to-back arrivals. First up is the much-anticipated Brie Larson debut as Captain Marvel, a movie tasked with great duties bridging the gap between the events of 'Infinity War' and 'Avengers 4', and possibly resurrecting the better half of the population who perished under Thanos' snap. Following the Carol Danvers outing, MCU fans should prepare for their biggest ensemble movie ever - the Infinity War sequel.
