“Avengers: Infinity War” is one of the biggest movies of the year so far, but in order to understand the events of the movie, you have to understand what the Infinity Stones are. In the movie, we see The Avengers team up with The Guardians of the Galaxy, Black Panther, and Doctor Strange to fight Thanos and The Black Order as well as to stop Thanos from collecting the Infinity Stones. Thanos plans to use these stones to kill half of all life in the universe. These six stones each control a certain power in the universe, such as time and space. In order to understand how they got to where they are, here are some movies you might want to watch before “Avengers: Infinity War”.
