Equilibrium (2002) Film

I haven't seen this for 15 years+ so thanks to Webster for the recommendation!

⁣In a futuristic world, a strict regime has eliminated war by
suppressing emotions: books, art and music are strictly forbidden and
feeling is a crime punishable by death. Cleric John Preston (Bale) is a
top ranking government agent responsible for destroying those who resist
the rules. When he misses a dose of Prozium, a mind-altering drug that
hinders emotion, Preston, who has been trained to enforce the strict
laws of the new regime, suddenly becomes the only person capable of
overthrowing it.
