​There are few things the Russo Brothers enjoy more than teasing Marvel fans as we await the release of Avengers 4. Last month, they posted a photo of Joe Russo sitting in the middle of the movie's set, which sparked speculation about the film's unknown title.

Now, another cryptic tweet from the Russo Brothers is out and it's even more puzzling than the last one.

​​Captioned "#wrapped," the photo is just an image that's crazy bright. It's confusing, but leave it to Marvel fans to speculate on its meaning.

​​Some believe it's War Machine's proton cannon ...

... while others are actively manipulating the photo to see if the meaning is hidden in plain sight.

We'd like to give ​a huge shout-out to the fans who are admittedly as confused as we are.

Whatever this image means, we are sure the Russo Brothers won't be the ones explaining it. Their
dedication to keeping mum on any details about theirs films is admirable—even if their stars aren't so great at secret-keeping.

Avengers stars have ​accidentally spoiled a few things about the movie.

Earlier this month, Chris Evans ​announced that the fourth Avengers movie would be his last as Captain America.

​​If the brothers plan to make their tweets even more ambiguous as the release date nears, they can keep them. Our eyesight is going to suffer is we keep squinting this hard.
