We also got a lot at one of the new pictures from Comic-Con. It is the same pose of Batman that we saw in the first picture, but from a different angle. It doesn't show much, but it is pretty cool.
Finally, production will go to Chicago in November. The city doubled as Metropolis in 'Man of Steel' and as Gotham in Christopher Nolan's 'Dark Knight Trilogy'. It will apparently double as both again this time around. Hopefully we get a teaser trailer soon!
