Actually, I think that's real... because I could swear I've seen that image before somewhere else within Time Warner. Some of the "Anyone can be chosen" promos have already started showing up on campus at Turner.
Remember, it may not be something directly for the film itself (so it not looking much like Reynolds means nothing). Warner/DC cross-promote stuff all the time, being owned by the same company.
I think this was done early on as artwork for some of the Summit meetings to plan marketing/promotions at Warner leading up to the film.
