A recent photo has emerged, from a location in Detroit that is very close to where Batman Vs Superman has been filming, showing a train with some graffiti on it that says "Batman" and "Robin". Director Zack Snyder is a huge proponent of dropping Easter Eggs in to his superhero movies look at the multiple Wayne Tech and Lexcorp references in Man of Steel for instance - and this would be a very cool one. However, although this is, more than likely, Snyder subtly hinting at Robins future appearance in the DC Cinematic Universe, it could just be some real world graffiti. Who knows?
