Prepare for “Avengers: Infinity War”: Every Marvel movie, ranked and explained

By Adam Epstein

Avengers: Infinity War, the biggest movie in Marvel history, is eyeing an enormous $500 million opening weekend. The culmination of 18 Marvel movies and dozens more characters and plot lines and easter eggs that have spanned a decade, the film is billed as “the most ambitious crossover event in history.” At least until the next one, that is.

If you’re one of the millions of people who will see the superhero film when it comes out Friday (April 27), you may need a refresher on all of the films that led up to this moment. There are a lot of them, and only a few are really worth watching before you go see Infinity War.

To help you figure out which previous Marvel films are worth your time, as well as the ones you should specifically revisit (or watch for the first time) ahead of Infinity War, Quartz has ranked and explained all 18 Marvel movies, from 2008’s Iron Man to this year’s mega hit, Black Panther.

Infinity War follows the Avengers as they team up with the Guardians of the Galaxy to thwart Thanos, an intergalactic being in search of the “Infinity Stones,” which together would grant him unlimited power over the universe. These stones have been scattered through the earlier movies, as detailed below.

The films are ranked from worst to best based on my opinion, but I also included Rotten Tomatoes ratings and how relevant their plot points are to Infinity War. Many of these films are eminently skippable, but the six top-ranked entries are certainly worth watching for anyone who likes superhero movies.

18. Iron Man 2  (2008)
