CHICAGO – March 19, 2018Avengers: Infinity War – Marvel’s most anticipated movie to date – is the culmination of a decade’s worth of storytelling.  The film will include over 70 superheroes who finally come face-to-face with the Mad Titan Thanos, the antagonist behind events leading up to the April 27th movie release.
