Marvel Cinematic universe will systematically expand to 67 characters who are going to appear in Avengers Infinity War and Avengers 4 as part of Marvel Phase 3. Captain America Civil War set the stage for Avengers Infinity War, the Russo Brothers said in a panel discussion “We thought the most compelling way to start off Infinity war would be to have the Avengers fight off each other when the greatest threat they will ever face shows up”.
They further clarified that there will be new titles for the final two movies as they are two independent movies without any major inter-linkages. There were many titles to choose from a host of comic-books related to the Infinity war storyline – Thanos Quest, Annihilation Conquest, Infinity Gauntlet, Infinity War, Infinity Crusade etc. Finally, the studio decided to name the third movie as “Avengers Infinity War” and the fourth movie is still untitled. This clearly indicates that Avengers 3 & 4 have completely separate storylines, they are not two parts of one grand story.
They have offered a good explanation as to why Avengers 4 is a separate project – “We wanted the movie to be very different and distinctive. There is certainly cross-pollination between characters and some story-arcs, but you know, the first movie is very clearly Avengers Infinity War and we will reveal what the second film is all about in some time. We don’t want to break the suspense.” Apparently, the first one is from Team Avengers perspective while the last one is entirely based on the Mad Titan’s character arc. It’s confirmed now that Guardians of the Galaxy will crossover with Avengers, this opens doors of possibilities for the makers. It will take the remnants of Avengers Infinity War but will create a whole new universe which will actually lay the foundation for Marvel Phase 4.
Avengers Infinity War will be released in May 2018, while Avengers 4 will follow it up in 2019. CHEERS!
