Man of Steel (2013)

Sadly, today, The DC Cinematic Universe has decided to go in a different direction. However, back when Man of Steel debuted in 2013, it was still in its infancy. While fans still have mixed feelings about the movie, many love a rather unexpected reference to another superhero that pops up during a scene set in space.
You see, when Superman is fighting in space, he leaps past a satellite. However, the interesting part is that it happens to have a logo from Wayne Enterprises on it. Of course, not long after Man of Steel, DC announced their new Batman and Superman movie, Batman v Superman: Dawn of Justice. Still, this was a full three years before the crossover of superheroes!
