A decade before Man of Steel, J.J. Abrams very nearly made a Superman movie. Abrams' script, titled Superman: Flyby was an action packed sci-fi epic that was intended as the start of a trilogy. How close did this film come to getting made? Very! Directors were in place, casting was underway, and props and sets were built. Den of Geek has a breakdown of both of Abrams' drafts, casting info, and quotes from those involved.
