One of my favorite movies is the 2002 science fiction film Equilibrium. Written and directed by Kurt Wimme, the film is set in a future society called Libria. In Libria it is against the law to feel.
The main character of the film named John Preston (played by Christian Bale) is a law enforcement officer. He is tasked with destroying objects that could incite emotion, including art, poetry and classical music. He is also required to kill rebels, known as “Sense Offenders”, who choose to experience illegal emotions.
The citizens of Libria have been brainwashed into believing that feelings are the cause of war, suffering and conflict. Accordingly, most of the citizens in Libria willingly participate in their own enslavement by taking a daily injection of a drug, known as Prozium II, which suppresses all emotion.
