Equilibrium is a 2002 American science fiction film[3] written and directed by Kurt Wimmer, and starring Christian Bale, Emily Watson, and Taye Diggs.

The film follows Bale as John Preston, an enforcement officer in a future in which feelings and artistic expression are outlawed, and a society where its citizens are forced to take psychoactive drugs to suppress emotion.

After accidentally missing a dose, Preston awakens and begins to uncover the suspicious inner workings of the regime governing the totalitarian state.

Established by survivors of World War III, the totalitarian city-state of Libria blames human emotion as the root of all conflicts.

It strictly outlaws all activities or objects that stimulate emotion, with violators labeled Sense Offenders and sentenced to death.

Libria is governed by the Tetragrammaton Council, led by "Father", who communicates propaganda through giant video screens.

The police force is led by the Grammaton Clerics, elite fighters trained in the art of gun kata.

Clerics frequently raid homes to search for and destroy illegal materials – art, literature and music – executing violators on the spot.

In 2072, John Preston is a high-ranking Cleric whose wife, Viviana, was executed as a Sense Offender, leaving him as a single parent of two.

He rushes home to destroy the hidden vials only to discover his son, who stopped taking Prozium after his mother died, already has.

Having anticipated the trap, Preston fights his way through an army of bodyguards to DuPont's office, confronting and killing Brandt in a katana battle.

The difference of a 63 percent increased lethal proficiency makes the master of the gun katas an adversary not to be taken lightly.Kata (型, かた) is a Japanese word for standard forms of movements and postures in karate, jujutsu, aikido, and many other traditional martial arts.

According to the visual effects supervisor Tim McGovern, who worked alongside Wimmer, the fascist architecture was chosen "to make the individual feel small and insignificant so the government seems more powerful".

[9] Equilibrium's locations include:[9] Although making a science fiction movie, Wimmer intentionally avoided using futuristic technology that could become obsolete, and he also decided to set his story in an indeterminate future.

[12] Elvis Mitchell of The New York Times dismissed Equilibrium for having heavily borrowed from Fahrenheit 451, Nineteen Eighty-Four, Brave New World and other science fiction classics.
