Have Scoot McNairy's Socks Revealed his 'Batman v Superman' Role?

With so many rumors going around about Batman v Superman: Dawn of Justice, one mystery that has remained unanswered is Scoot McNairy's role in the film. The Argo actor joined early this summer and the immediate thought was that he could possibly be suiting up as the Flash because the first idea whenever someone joins a superhero film is they're playing an established character. In this case, though, recent evidence suggests the Flash rumors may have been true.

A set photo uncovered by Batman News shows McNairy on set, sporting normal civilian gear until you look down at his legs. There you can see his pants have been cut short and underneath are the bright green fabric typically used as digital markers for future CGI enhancement. Why would McNairy need that unless his legs were about to do something out of the ordinary, like move at super speed?  It's possible they could be mechanical appendages but that seems unlikely compared to the alternative, which is that McNairy could actually be playing Flash.

For what it's worth, Badass Digest "confirms" that Flash does appear in the film but backs off on saying it will definitely be McNairy. They also say Green Lantern won't be showing up until Justice League, which seems like an odd way to introduce such a major character. Then again with Warner Bros. announcing a ton of release dates for future DC Comics movies all of that could change. A Green Lantern/Flash crossover film has been mentioned as a possibility for 2017 although that has not been verified by the studio.

Batman v Superman: Dawn of Justice opens March 25th 2016.
