On May 2, 2018, Marvel Entertainment will celebrate the 10-year anniversary of the original Iron Man. Two days later, the comic-book movie studio will release Avengers: Infinity War, the ultimate payoff to a decade of work that all started when, at the end of Iron Man, Samuel L. Jackson's Nick Fury asked Robert Downey Jr.'s Tony Stark to join the "Avengers initiative." The post-credit scene would never be the same, and neither would popcorn entertainment, as the first trailer for Avengers: Infinity War makes clear.
Avengers: Infinity War is the first of a two-parter dealing with the arrival of Thanos, the purple alien being who has lurked in the shadows of the Marvel Cinematic Universe films since Joss Whedon's 2012 film, The Avengers (and made an actual appearance in Guardians of the Galaxy). Thanos wants what all 10-foot-tall, bald, lavender autocrats want: a shiny gold gauntlet with slots for galactic power jewels. After many movies of not finding any of the legendary "Infinity Stones," the Infinity War finds Thanos wielding the spacetime-bending MacGuffins in a most destructive way. The superheroes are screwed. But every single frame of this trailer makes the case that Avengers: Infinity War is the Lord of the Rings of superhero movies.
