Previously rumored as Nightwing for Batman Vs. Superman, now it's looking likely that Scoot McNairy might be playing the Justice League speedster The Flash.

A set image of Scoot McNairy reveals an interesting detail in that the actor is wearing green-colored "CGI socks."

The socks are the same color as green screens, which are used to add digital special effects.

We can speculate that some sort of special effects may be added in for The Flash and McNairy's legs.
