Considering the fact that Zack Snyder kept to the comic book script, Snyder was shocked that more fans didn't suspect the death of Superman. For Snyder, he knew that Superman had to die in order for Justice League to emerge. In an interview, Snyder said, "I was shocked that people did not immediately jump to the conclusion. I think they just felt like, ?That?s impossible. They?re not going to kill Superman.?"
