What does one tweet and a two green socks tell us about Batman v Superman: Dawn of Justice? Plenty, if you're a comic book fan who's open to wild speculation about this kind of stuff (read: we are). 

Cosmic BookNews set the nerd world on fire today by pointing out the special green socks Scoot McNairy (best known for roles in Argo, and Halt and Catch Fire) was wearing in this photo from the set of the movie:

The reason this is news: the socks are the same color as green screens, which suggests that some sort of CGI effect is being used on McNairy's legs, which suggests he might be playing super-fast superhero and Justice League member The Flash

It makes even more sense that The Flash would show up in Batman v Superman now that we know Zack Snyder will be directing a Justice League movie next. 

Batman v Superman, starring Ben Affleck as Batman, Henry Cavill as Superman and Gal Gadot as Wonder Woman hits theaters in May 2016.
