SUPERMAN THE MOVIE- THE SCRIPTS

1974/1975
Screenplay by Mario Puzo

Mario Puzo excepted the job, he turned in 2 drafts for both Superman 1 and 2, after which, he was exhausted and declined any further major involvement. He did visit the sets and might have been involved in shaping the script for a day or 2 on set in 1977.
Scripts very rare, do you have it?

July 1976
Screenplay by Mario Puzo, David & Leslie Newman and Robert Benton
Director: Guy Hamilton

Before Richard Donner and Tom Mankiewicz made revisions to this version, Guy Hamilton was to direct. Guy Hamilton dropped out because Production moved from Italy to England, and he couldn't shoot in England because of tax reasons. The Newmans worked with Robert Benton, he was involved with the first film's script for a short while before moving onto his own projects.

April 1977
Screenplay by Mario Puzo and David & Leslie Newman
Creative Consultant: Tom Mankiewicz
Director: Richard Donner

The Writer's guild rule allows only 4 writers to be credited, hence Tom Mankiewicz has Creative Consultant credit. Tom and Donner revised the screenplay. This script is dated April, but revisions began in late 1976. Further revisions throughout the early part of production. Donner would've ideally wanted more time to shape the script but there was very little time, production had to move very quickley.
