The cameos successfully broadened the DCEU roster in one fell swoop, but the film featured another, more subtle cameo: that of director Zack Snyder himself.
Before the DC Extended Universe was officially created, Zack Snyder was one of the people responsible for setting it into motion.
Then again, perhaps we’ll all see Snyder make a much more significant cameo when Justice League finally hits screens next year.
Snyder’s second DC-related film Man of Steel introduced the world to Henry Cavill as Superman but stopped short of introducing bigger things, like a world filled with recognizable DC characters.
