As one of the breakout movies of 2023, Anatomy of a Fall has attracted popular international attention, yet its appeal is arguably limited by its R-rating. A legal thriller centered around the excavation of complex interpersonal relationships, most of the movie's action takes place in the typically reserved atmosphere of a courtroom. Nevertheless, throughout its 150-minute runtime, Anatomy of a Fall does more than enough to earn its R-rating – a categorization that actually enhances rather than diminishes the onscreen drama.
