So there is a quote engraved into the Superman suit which was put there by Snyder.The quote from Joseph Campbell that Wilkinson integrated into the costume speaks to the film's themes with respect to the character: "And where we had thought to find an abomination, we shall find a god; where we had thought to slay another, we shall slay ourselves; where we had thought to travel outward, we shall come to the center of our own existence; where we had thought to be alone, we shall be with all the world."
And Snyder said : "Joseph Campbell says this about the hero’s journey and I always thought it was super-appropriate for Superman. That’s his whole story in a nutshell"
And this is what Campbell has said about a hero's journey :
Joseph Campbell defined a classic sequence of actions that are found in many stories.Eg Luke Skywalker in the Star wars trilogy.
I. Separation / departure
The first section of the story is about the separation of the hero from the normal world. Separation has symbolic echo of infant transition away from the mother and so has a scary feel to it.
I.1 The Call to Adventure
I.2 Refusal of the Call
Acceptance of the Call
I.3 Supernatural Aid
I.4 Crossing of the First Threshold
I.5 Entering the Belly of the Whale
II. Initiation
In the main part of the story the hero is initiated into true heroic stature by various trials and rites. Through daring and battle, the true character emerges.
II.1 Road of Trials
II.2 The Meeting with the Goddess
II.3 Woman as Temptress
II.4 Atonement with the Father
II.5 Apotheosis
II.6 The Ultimate Boon
III. Return
After initiation the hero can cleansed and return in triumph to deserved recognition, although this in itself may not be without its trials and tribulations.
III.1 Refusal of the Return
III.2 Magic Flight
III.3 Rescue From Without
III.4 Crossing of the Return Threshold
III.5 Master of the Two Worlds
III.6 Freedom to Live
