The Machinist (2004)

The Machinist is a psychological thriller that functions as a study of guilt and moral conscience. Trevor Reznik cannot sleep because a year prior, he fatally struck a child with his car and fled the scene. Everything he experiences — the hallucinations, the extreme physical deterioration (Christian Bale lost 28 kilos for the role), the paranoia — is a manifestation of a conscience that cannot be silenced. The film precisely constructs a narrative where modern man attempts to flee from his moral responsibility and discovers he cannot. The arc is classic: sin, denial, inner torment, confession, expiation. Only when Trevor surrenders to the police and accepts the consequences of his act can he finally sleep. It is a morally orthodox film disguised as an atmospheric thriller. The violence is psychological rather than physical, yet there are disturbing scenes: the accident where a colleague loses an arm, the child's hit-and-run in flashback, and the protagonist's physical deterioration. The relationship with a prostitute adds moderate adult content. For mature audiences capable of discerning between the darkness depicted and the underlying message about the inescapability of moral conscience.
