The Warner Brothers, Legendary Pictures, DC Comics and Syncopy Inc logos are shaded steel gray and appear in swirls and bends of Kryptonian metal.
If you look closely, the Warner Brothers, Legendary Pictures and DC Comics logos have Kryptonian writing.
The film title and the Superman shield briefly appear in the closing credits (in parallel to all the other Superman films where they appear in the opening credits).
Right before the credits end you can hear "uh-oh" being spoken mysteriously by a child. The same sound can be heard in the track "Oil Rig" from Hans Zimmer's score for the film.
