The marketing people at Warner Bros were so sure that Man of Steel had some promising Christian allegory angles that they tried to sell it that way to pastors, even offering them sermon notes. I wasn’t that surprised since Supes has a long history of being compared (wrongly in my opinion) to Jesus. Then I went to see it and realized that if this was supposed to be allegory then they missed the mark by several light-years. Rather than just be a critic, though, I decided to offer them some assistance. Here you go Warner Bros. Here is how you write Superman as Christian allegory:
Man of Steel 2: The Last Son of Krypton
In the opening scene we see an act of terrorism committed against a Lexcorp facility in a foreign country. Superman flies in and does his thing, but damage is done to Lexcorp assets in the process. We are taken through a montage showing military conflict in that region between America and insurgents with Lexcorp military contractors in the mix. Clark & Lois Lane are sent to be war correspondents. We meet Lex Luthor and it is shown that he is instrumental in getting congress to go to war to protect Lexcorp interests.
The conflict escalates and Supes keeps getting involved, but is torn about who he should be protecting. He discusses this with Jor El who tells him it is his role to show them how to resolve their conflicts better. He chooses to try to protect both sides and the result is a lot of damage to Lexcorp assets. Next we see Lex Luthor before a committee of congress arguing that Superman should be held responsible for the damage, and a debate arises whether as an American citizen he should be required in such conflicts to defend American interests. Supe flatly refuses to take orders from the military.
Luthor intentionally escalates the conflict and puts Superman in a position where a lot of collateral damage is done by building drones and robots and targeting insurgents and terrorists in civilian areas. Superman defeats these robots and uncovers Luthor’s war crimes getting him thrown in jail.
Tension rises between Clark and Lois when she writes a piece questioning the patriotism of Superman since he isn’t fighting unequivocally for American interests. In response Superman holds a press conference where he renounces American Citizenship claiming to uphold Truth & Justice for all the people of Earth. American response to this is outrage, and the military tries to exclude Superman from acting in military zones, fighting him when he appears, the resulting collateral damage is catastrophic and includes Lois Lane who is hospitalized.
Clark, in crisis, realizes that his own “heroic” actions are actually endangering lives and renounces violent intervention entirely. He commits himself to only acts of mercy and nonviolent disruption, doing things like carrying children out of combat zones using his body as a shield, but refusing to attack or arrest anyone. He destroys drones, cripples tanks, disables missiles etc… Lois finds a way to talk to Jor El to try to understand what Superman is doing. She argues that fighting for the US if imperfect is still the best way to bring good to the world and what Superman is doing is just making him hated by everyone. Jor El explains that even though Kal El was raised in Kansas, he was sent to all the people of Earth and the only way he can be true to the people of Earth is to act as a Son of Krypton, an outsider, and not take sides.
The colonel we met in Man of Steel receives a message from Luthor offering to get rid of Superman for him. Luthor hatches a plot to catch Superman using Lois Lane and Kryptonian atmosphere (the new Kryptonite), and his super-robots to publicly destroy Superman. It nearly works, but at the point where we think Superman will win and escape he and Lex Luthor meet and Luthor jams the surveillance equipment the military is using to watch the engagement. While in private Luthor talks to Superman convincing him that the myth of Superman will always undermine the very things it is supposed to stand for. People will just want him to save them, they will never stand for justice and mercy as long as there is an invincible hero to do it for them. They will only love him if he takes sides and fights on their behalf, but if he tries to renounce fighting they will revile him and reject him. Luthor convinces him the best thing is for him to “die” so that people are forced to fill the savior void with their own just actions.
When the signal jamming ends Luthor is holding the shredded and bloody costume of Superman who is gone. The world mourns the death of Superman. The president orders the end of the war against the wishes of Lexcorp and Lois finds a note and some token from Clark letting her alone in on the secret that he is still alive. The last thing we see is Clark flying through space, perhaps to go explore the ruins of Krypton.
