Zack Snyder, who has directed three different movies for the DC Extended Universe, took some time to wish Gal Gadot (Diana Prince/Wonder Woman) a happy birthday―and in the process, gave fans a little peek of a deleted scene from Justice League.

The actress, who has appeared in Snyder’s Batman v Superman: Dawn of Justice and Justice League, as well as Patty Jenkin’s Wonder Woman, celebrated her birthday on Monday, April 30. She is now 33.

Posting on his account on Vero, a social media platform geared toward artists, Snyder wrote “Happy birthday to my amazing friend” and posted a black-and-white photo of Gadot as Wonder Woman. She is standing in an unknown, dark location, holding a torch; paintings can be seen on the wall behind her, including of what seem like robed figures. Gadot/Wonder Woman seems confused or worried by whatever unseen thing she is looking at.

Whether or not Snyder just grabbed the first picture he could find of Gadot or whether or not he wanted to whet fans’ interest, many will no doubt be wondering what the context of this picture is. One possible theory is that this is the Shrine of the Amazons, where Wonder Woman’s mother, Queen Hippolyta (played by Connie Nielsen), sent a warning arrow to alert her daughter about the arrival of villain Steppenwolf (Ciarán Hinds).

Though Snyder is the only credited director on Justice League, he was replaced partway through production by Joss Whedon, due to the untimely death of Snyder’s daughter. Snyder had already been planning edits and reshoots; under Whedon and Warner Bros., they turned out to be quite extensive, which some believe significantly altered Snyder’s original plan. Given how divisive Snyder’s work in the franchise is, this may or may not be considered a good thing.

In any event, Snyder has been active on social media lately, sharing hints about what his plans were and pointing out the hidden significance of various scenes. It is quite possible that, aside from being a nice birthday wish, this too was meant to give fans something to wonder about.

Gadot has become the breakout star of the franchise, with Wonder Woman its only unqualified success. Because of this, Wonder Woman 2 is getting fast-tracked, and will be released on November 1, 2019.
