The Machinist is a 2004 psychological thriller film directed by Brad Anderson. Christian Bale plays Trevor Reznik, an industrial worker suffering from severe insomnia and psychological distress. Bale's performance in this film is nothing short of astonishing, as he underwent an extreme physical transformation to portray the emaciated and sleep-deprived character. The Machinist is a haunting and atmospheric film that keeps viewers on the edge of their seats, with Bale's committed performance being a standout element.
