Have you tried google yet? Though i havent visited many, im aware that there are sites which have nothing but loads of movie scripts on them. Idk their sources but maybe it'll help.
Thanks. That however is the script. I was looking for the Shooting Script. I was unable to find the shooting script anywhere online.
No worries though. I actually purchased The Annotated Godfather: The Complete Screenplay with commentary on every scene, interviews and little-known facts. It should be on every film makers book shelf. I also bought The Godfather boxed set.
