In page Alfred Bester:

"

Bester's eyesight began failing in the mid-1970s, making writing increasingly difficult, and another layoff from published writing took place between early 1975 and early 1979. It is alleged during this period that the producer of the 1978 Superman movie sent his son off to search for a writer. The name Alfred Bester came up, but Bester wanted to focus the story on Clark Kent as the real hero, while Superman was only "his gun." The producers instead hired Mario Puzo, author of The Godfather, to write the film.[citation needed]
