As such, activities or behaviours which can be seen as commonplace enough to be part of mainstream will not be served to place films in this list, such as strict homosexuality or less extreme themes and situations involving older/younger relationships for example. A fair definition of the word 'perversion' in the sense I am applying it would be: aspects of the human psyche and/or human behaviour deviating greatly from what is regarded as normal or right. These titles contain scenes, themes, and general human behaviour which can be described as 'perverted' in the broader sense, relating to the human psyche, and as such, not exclusively examples of sexual perversion, as there are many forms of perversion existing in the human mind which provoke shock, disgust, disbelief, and bewilderment in the average viever.
