Superman that never was...

Supergirl: "And that's for making me star in that really bad Supergirl movie!"

Over at Trektoday.com they had a link to the review of the early terrible script by JJ Abrams. (LOST, and MI:III) http://www.aintitcool.com/display.cgi?id=13350

The script he’s talking about sent WB into a nervous frenzy. They tried their best to repair the damage, but it was too late and the script was scrapped.
