The nature of the director in any form — movies, television, stage, radio — is to serve the spirit of the script. 

A director is not the master of the script — the director must be a slave to the written word in order to understand the greater purpose of the writing.

Many directors believe they are co-authors of a work and that is wrong. 

Weak authors create strong directors and that wrongful power dyad is always terrible for the script.

A script is not a blueprint or an architectural dream.

A script is the bones, sinew, muscle, heart and being of any project.

For anyone other than the author to change the work in situ or to re-arrange established ideas on the page is to threaten the very core of the project that risks creating the common and the ordinary failure that reeks in the marketplace and is immediately forgotten by those in the audience who writhe and yearn for meaning in their escape into entertainment.
