The so-far-untitled Avengers 4 directors, the Russo Brothers, tweeted images to celebrate the end of filming the upcoming superhero flick.

Along with the caption, “#wrapped,” the pair uploaded a photo of something very bright.

Fans on Twitter have some thoughts about what these clues could mean for the Avengers film. A few thought it could point to Adam Warlock (AKA “Him”), who was referenced at the end of Guardians of the Galaxy 2 and rumored to appear in the third film in the franchise.

Other fans suggested it could be a coffin or any other object of the same shape.

Previously, the duo posted a cryptic photo on social media that teased the title of the Infinity War conclusion.

At the end of the day, I guess we’ll have to wait until the film’s release May 3.
