On Blu-Ray and DVD February 22
The origins of this lie in a revamp of Superman, Superman Now, which began when Morrison and editor Dan Raspler were unsuccessfully brainstorming ideas for a new take on the character outside the San Diego Comic Con, when they had a "shamanic" encounter with a man dressed as Superman which helped spark the creative process and inspired the cover to the first issue:
"He was perched with one knee drawn up, chin resting on his arms. He looked totally relaxed... and I suddenly realized this was how Superman would sit. He wouldn't puff out his chest or posture heroically, he would be totally chilled. If nothing can hurt you, you can afford to be cool. A man like Superman would never have to tense against the cold; never have to flinch in the face of a blow. He would be completely laid back, un-tense. With this image of Superman relaxing on a cloud looking out for us all in my head, I rushed back to my hotel room and filled dozens of pages of my notebook with notes and drawings."
[Source: Wikipedia] Dr. Leo Quintum and his team from P.R.O.J.E.C.T. are exploring the Sun when they are sabotaged by a booby-trapped, genetically enhanced Lex Luthor clone. Superman saves the day, but finds out he has a new power: the ability to project his bioelectric aura. Lex Luthor (used by General Sam Lane to work for the government) has orchestrated this to overwhelm Superman's cells with a massive amount of yellow solar radiation. Dr. Quintum determines that Superman's newly enhanced power is also killing him, and that he has about one year to live. Lex Luthor is arrested, thanks to Clark Kent's article. Superman decides to keep his impending death secret from the public. However, Superman reveals his secret identity to Lois Lane because he wants to spend his remaining time with her. Lois refuses to believe that Clark and Superman are the same person, and suspected him of playing a birthday trick on her. For her birthday, Superman takes her to the Fortress of Solitude. During this visit Superman's secretive behavior heightens Lois' suspicions. She becomes paranoid after she is exposed to alien chemicals in the air which play on her fears. Her paranoia causes her to attack Superman with a kryptonite laser. Superman learns that his newly enhanced powers have rendered him immune to green kryptonite. Superman is able to calm her down and reveals that his secret was that he has been preparing her birthday present: superpowers for 24 hours. Now as a Superwoman, she and Superman stop a monster attack in Metropolis just as Samson and Atlas arrive. Flirting with Lois, and showing a newspaper that reads "Superman Dead, by Clark Kent", Samson is revealed to be the one who stole jewels from an Ultra-Sphinx. Kidnapping Lois; the Sphinx demands an answer to the question: What happens when the unstoppable force meets the immovable object? and Superman answers: They surrender, Lois is saved. Superman then defeats Atlas and Samson in a double arm-wrestling match for Lois' company. Superman and Lois then go from the ocean depths to the moon and kiss before her powers fade and she falls asleep. Superman flies her home without being able to ask his question.
