A Dystopian crime film, maybe
In this movie from 1972 (no I didn't see it when it came out, too young). The government has a new therapy to treat violent criminals. Yes it is set in the future; a sadistic gang leader runs out of luck and is imprisoned for murder, his sentence being for 14 years. While serving his sentence he learns of and volunteers for a conduct-aversion experiment in order to get out early.
This new technique is called the Ludovico technique, whereby the person being treated is strapped to a chair, injected with drugs, and forced to watch films of sex and violence with his eyes propped open in an effort to make them nauseated by the films content.
Shortly after treatment he is released from prison where he encounters people from his past including his victims. They of course haven't had any treatment against violence and seek to inflict their own brand of justice, and his ordeals begin. He ultimately ends up in hospital, whereby he discovers that he is no longer adverse to violence and sex.
Stanley Kubrick the director is quoted as describing the film as:
- "A social satire dealing with the question of whether behavioral psychology and psychological conditioning are dangerous new weapons for a totalitarian government to use to impose vast controls on its citizens and turn them into little more than robots."
Which is indeed quite a good description. If you haven't seen the movie, grab a copy of it and watch it.
