What is the storyline of Avengers: Infinity War?
The movie is set to unite the Avengers, the Guardians of the Galaxy, and a number of other Marvel superheroes.
As a result it’s tipped to be one of the company’s biggest blockbusters ever, especially given its £400m budget.
The “goodies” will be pitted against Thanos, a villain that Marvel has been teasing since the post-credit scene at the end of the first Avengers in 2012.
The new film will see supervillain Thanos seeking to wield the power of the six infinity stones that control Time, Space, Mind, Soul, Reality and Power.
The film, which is directed by the Russo Brothers, takes place four years after the second Guardians of the Galaxy film.
The Infinity Gauntet was a six-issue comic series that was published in 1991.
The story will carry onto a third Marvel film in 2019, that doesn’t have an official name as of yet.
