An unconfirmed twitter account claiming to be The Russo Brothers mysteriously tweeted an image that many are suspecting to be the very first image for their upcoming film, Avengers: Infinity War. Though Anthony and Joe Russo haven’t verified the account, it has in the past released photos from parts of Captain America: The Winter Soldier, and Captain America: Civil War, which were later to be found in each movie.

It’s unclear what exactly this image is portraying. In their previous reveals the account used hyper-zoomed in shots or looks at the sets.

Avengers: Infinity War Part 1 will be released May of 2018.
