Batman V Superman: 10 Completely CGI Moments You Didn’t Notice

Of course, Snyder didn't actually blow up Capitol Hill during the production of Batman V Superman, but it's pretty surprising to learn that he didn't even go there. As this side-by-side shows, all they actually had were some steps, some punters and a load of extras with signs. The building and the weather were both added during post-production.

Even Superman's entrance into the scene was achieved digitally. While there might have been a way to rig some cranes and some wires and make it look like Henry Cavill was flying in, instead they opted to just add him digitally later. Again, it was probably the cheaper option, and it looked fine in the end.
