Avengers: Infinity War and Avengers 4 directors Joe and Anthony Russo just posted a set photo from Avengers 4 telling fans to “look hard.”

And fans are definitely looking hard as they’ve cobbled together a number of theories about what could be hidden in the seemingly innocent photo. One user theorizes the photo is just confirming it’s from Avengers 4 and he points out that there are 4 A’s.

One user believes they revealed that the Avengers 4 title will be Endgame. Avengers: Endgame is one of the top rumored titles as it references Doctor Strange’s statement to Tony Stark after he hands over the Time Stone to Thanos.

A number of other fans believe it doesn’t have anything to do with the Avengers, but rather the X-Men since Disney finally closed their deal with Fox to reacquire the mutants.

Some of the theories were a little far out there, a number of fans indicated that Homer Simpson would be appearing in Avengers 4

Others had quite a bit of fun with the photo referencing one of the funniest lines from Avengers: Infinity War:

Another hinted at what they think is on Joe Russo’s laptop.

Others pointed at an engine and what they are calling a mechanical flamingo.

One user believes he found multiple hints in the photo including a dead body, equipment for the Quantum Realm, and a bottle for the quantum healing particles.

Plenty of other users were just perplexed by the photo:

The Russo Brothers haven’t confirmed nor denied any of the theories at this moment.

What in the world do you think they are teasing with this photo? Do you think they revealed the title for Avengers 4? Could it be hinting at the X-Men?
