Good psychological drama thriller with great direction and story.
What makes this movie even better is Christian Bale.
Top notch acting and horrible physical transformations.
According to the review he lost 60 pounds, which brought him down to around 120 pounds, which is inhuman for someone who is 6 feet 3 inches tall.
Bale wanted to get down to 45, but the producers wouldn't let him because it was too dangerous for him.
Bale then regained weight and gained muscle to play Batman.
The plot revolves around Trevor, who has been unable to sleep for a year.
Fatigue severely deteriorated his body and mind.
One day, his colleagues turn on him because one of them lost an arm in an incident involving Trevor.
When Trevor seems to discover a plot against him, he feels guilty, becomes suspicious and then paranoid.
