Auteur Theory

The Auteur theory is when the director of a film can be assigned the role or "title" of an author.
"The strong director imposes his own personality on a film; the weak director allows the personalities of others to run rampant."
To be considered an Auteur, the film maker must have some kind of work which can be analysed for themes that are ongoing. These themes can be intentially or unintentially. An Auteur must have a differentiating style, which can be almost instantly recognisable.
The Auteur theory has many criticism's and problems with it.
