So far, the Batman v Superman team has done a good job of keeping key details about the film a secret. But that doesn't stop fans from speculating.
After several reports regarding Aquaman's presence in the film, the focus has shifted to rumours about another big-name DC superhero appearing in the upcoming movie.
Actor Scoot McNairy's role in Batman v Superman: Dawn of Justice is still a mystery, but a new on-set photo of the actor, taken on 18 August 18, reveals a major clue, according to Batman-news.com.
Here's what those green socks mean: the special effects team are going to digitally do something to those legs during post-production. Now what could that really mean?
One, among several possibilities, is that McNairy might actually be playing: The Flash.
We know that the BvS team is filming some major action sequences set amid a lot of destruction and chaos. Maybe those scenes will feature The Flash in action trying to save lives – it might be a key scene that reveals the speeding superhero to the audience. Just a theory.
However, seeing that The Flash is one of the primary superhero characters and member of the Justice League, maybe it's not unwarranted to assume that director Zack Snyder definitely has a part for him somewhere in the film.
