Is Superman "Christian"?

I've (yet) to see the new Superman movie, but I did spot this blog post on CNN:

Baltimore, Maryland (CNN) - As the new Superman movie takes flight this weekend, filmmakers are hoping the Man of Steel lands not only in theaters, but also in pulpits.

Warner Bros. Studios is aggressively marketing "Man of Steel" to Christian pastors, inviting them to early screenings, creating Father’s Day discussion guides and producing special film trailers that focus on the faith-friendly angles of the movie.

The movie studio even asked a theologian to provide sermon notes for pastors who want to preach about Superman on Sunday. Titled “Jesus: The Original Superhero,” the notes run nine pages.

“How might the story of Superman awaken our passion for the greatest hero who ever lived and died and rose again?” the sermon notes ask.

I suggest you read the entire post, where some of the Christian allegory in the movie is explained. Here is a small sample:

The movie focuses on the origins of Superman, who was sent from the planet Krypton as an infant to save his species.
He is raised by surrogate parents who help him grapple with his special powers, even though they don’t fully understand the source of his extraordinary abilities.

When he turns 33, Superman must willingly sacrifice himself to save the human race. 

 Of course the Miami Herald argues for Superman's Jewish roots:

Much as the baby prophet was floated in a reed basket by a mother desperate to spare him from an Egyptian Pharaoh’s death warrant, so moments before Kal-El’s planet blew up, his doomed parents tucked him into a spaceship that rocketed him to the safety of Earth. Both babies were rescued by non-Jews and raised in foreign cultures — Kal-El by Kansas farmers named Kent — and all the adoptive parents quickly learned how exceptional their foundlings were. The narratives of Krypton’s birth and death borrowed the language of Genesis. Kal-El’s escape to Earth was the story of Exodus.

Clues mounted from there. The three legs of the Superman myth — truth, justice and the American way — are straight out of the Mishnah. “The world,” it reads, “endures on three things: justice, truth and peace.” The explosion of Krypton conjures up images from the mystical Kabbalah where the divine vessel was shattered, and Jews were called on to perform tikkun haolam by repairing the vessel and the world.
