First 'Avengers: Infinity War' Trailer Unleashes Thanos' Wrath

The Avengers are calling everyone they know for this one.

The first trailer for Avengers: Infinity War is basically a roll call of the Marvel Cinematic Universe, and all the players have one goal: to stop Thanos (Josh Brolin) and his Infinity Stone-powered rampage across the galaxy.

The film from the Russo Bros. is written by Christopher Markus and Stephen McFeely, who penned the three Captain America movies.

Pre-pandemonium was at an all-time high ahead of the release, with Spider-Man actor Tom Holland causing a stir with a creative way to reveal the film's new poster, while a retrospective video showing fans reacting to old trailers is closing in on 500,000 views on YouTube in a matter of hours. 

Marvel Studios is opening the film May 4. Watch the trailer above.
