The Avengers was the real beginning of the ‘Marvel movie’ as we know it

Ten years ago, the Avengers first assembled on movie theater screens around the world. Marvel’s The Avengers made $1.5 billion in May of 2012 and, whether anyone likes it or not, changed how audiences think about movies. But the success of the movie didn’t just change our world, it changed how Marvel produced their fictional one, as well.

The Avengers was proof that audiences didn’t just want one-line references to other comics or visual Easter eggs buried in the background of shots. They wanted an entire world depicted on screen, and they wanted to see their favorite characters interact in it. But, most crucially, it turned the Marvel movie — and the idea of the superhero movie, in general — from a solo story into a crossover ensemble film. Every Marvel movie is now an Avengers movie, to some degree.

The 2012 Avengers was the sixth installment in, and culmination of, a sequence of movies now referred to as “Phase 1” of the Marvel Cinematic Universe. Each movie preceding The Avengers introduced characters who would then “assemble” in the final movie, which was written and directed by Joss Whedon, with a story by Zak Penn. The movie’s basic plot is both fairly straightforward and, also, sort of a rats nest.
