VIDEO : 'Avengers 4' Directors Tease Marvel Fans To Look For Clues In New Photo

Avengers 4 is one of the most hotly anticipated Marvel Studios films coming in 2019. And the Russo Brothers are having some fun with the fans in this latest tease from the film.

Joe Russo shared a new image from the set of Avengers 4 with the caption "Look hard...".

Comicbook.com says turns out there are four different A's throughout the photo, adding up to Avengers 4. Clever right?

The A's are located towards the top right of the photo (by the duct), in the ladder on the right, in the Easel on the left, and by the camera on the far left.

But this doesn't answer any mindbending questions of course, like who will survive after Avengers 4.
