It's on the Bonus Features Blu Ray. Here is the best description I could find. It's called “Journey of Discover: Creating Man of Steel"
A side-by-side documentary of sorts with the filmmakers and cast that takes you behind-the-scenes in a way that is far more engaging than the usual commentary track. Here we get to see simultaneous footage of things like pre-viz, wire work, and behind-the-scenes filming alongside the finished film in addition to commentary. This actually extends the length of the movie as sometimes the film cuts out altogether and moves to documentary footage and talking heads, but it’s an in-depth insight that was missing from the shorter featurettes.
Btw, I highly recommend sitting down and watching it. It is a lot of fun to watch if you enjoy watching how movies are made as this is quite in depth.
