- All-Star Cast: The story was penned by the legendary Alan Moore, who wrote some of the most thought-provoking Superman tales, and iconic Silver Age Superman 1950's comic book artists Curt Swan and Kurt Schaffenberger. Perhaps the most fitting farewell to the classic Supes you can get.
- What Could Have Been: Jerry Siegel, Superman's co-creator and original writer, was offered the chance to write this story (and wanted to accept), but unfortunately couldn't for legal reasons.
- Word of Dante: Alan Moore in interviews clarified that regardless of how DC classifies and manages its continuity, he wrote the story under the intent that it is Superman's last adventure and true ending for the entire mythos.
