Screenplay codes and conventions

Above there is a section taken from the Superman film in which I have analysed to show what should be included in which is included in the slide below

This is showing the codes and conventions of a film script and where these are included, they should be included in each script for the following reasons:

• Page numbers -
  For reference in which page the actors/directors or need to be on. 

• Stage directions -
  For reference to know where, what and how the actors need to be doing
• Character names-
  To know who is speaking for the crew to know who to show in the shot
• Directors notes -
  For the crew, director and everyone else to be aware of what needs to be done for improvement.
• Way of speech -
  The way the character must speak the line to know the effect for the scene

This is a phony script I made copying the codes and conventions of a movie script.
