William Hays and his code

William hays from 1921 was the first president of the Motion Picture producers and distributors of America in which time he brought out the Motion Picture Production code or 'Hays Code'.
This Code was enforced in 1933 and its main principle was that no film could exploit women, lower human morals, ridicule laws, religions or other humans.
List of principles of the Hays code

This Motion picture production code affected all films being made shown in America, meaning that films already made where edited so they adhered to the codes rules, up until 1968 when the code was stopped.
Famous films that where edited are Baby Face' and 'Scar-face', which in the new edit lost the meaning behind the stories and sometimes even the ending.


'Baby Face'
Early in the film, Lily seeks the advice of the only man she trusts, a cobbler played by Alphonse Ethier. He reads a passage from a book by the philosopher Nietzsche. The first version of the cobbler's speech that did not pass New York State Censorship was as follows:^[2]

A woman, young, beautiful like you, can get anything she wants in the world. Because you have power over men. But you must use men, not let them use you. You must be a master, not a slave. Look here — Nietzsche says, "All life, no matter how we idealize it, is nothing more nor less than exploitation." That's what I'm telling you. Exploit yourself. Go to some big city where you will find opportunities! Use men! Be strong! Defiant! Use men to get the things you want!

To:

A woman, young, beautiful like you, can get anything she wants in the world. But there is a right way and a wrong way. Remember, the price of the wrong way is too great. Go to some big city where you will find opportunities! Don't let people mislead you. You must be a master, not a slave. Be clean, be strong, defiant, and you will be a success."

The new lines were dubbed onto an over-the-shoulder shot of the cobbler. This was one of several changes that allowed the film to pass the New York State Censorship Board.
