What began in 2008 with Iron Man will begin to come to a close in 2018 with the release of Avengers: Infinity War. The first of a two-part finale to an unprecedented 22-movie story arc spanning the Marvel Universe, the film will unite essentially the entire MCU in a fight against the Mad Titan Thanos. Heroes will die. Stories will end. It’s no small coincidence that this trailer is dropping as Black Panther’s run at #1 begins to come to a close. Marvel is clearly trying to keep the momentum of its unexpected phenomenon going, and has moved up the release date of Avengers: Infinity War one week, so that we’re only six weeks out from the BIGGEST film of the year. This trailer is very Thanos-centric, fully introducing the threat first seen at the end of The Avengers six years ago. Avengers: Infinity War will open April 27, 2018.
