“Andrew Kreisberg told me that the name of the episode is ‘Supergirl Lives,'” Smith said. “I’m gonna cry talking about this. The name of the script I wrote back in 1996 was called ‘Superman Lives.'”
Smith was brought on board to write a script for Superman Lives before Tim Burton and Nicolas Cage got involved. He tells the story in great detail on the An Evening With Kevin Smith DVD. Definitely worth watching him tell the story.
