The aim of this article is to show the structural similarities between legal discourse and film, and cinematographic works that can be useful in teaching law. For this purpose lacanian psychoanalysis is used (in the version presented by Slavoj Žižek) and the movies – Triumph of Will, Battleship Potemkin, Bezmiar sprawiedliwości, Twelve Angry Men and Dead Poets Society. Based on the three-level concept of meaning i.e. Imaginary, Symbolic and Real levels, the author shows that the centre point of legal discourse and film is the Great Other. Motion pictures as well as the law require their subjects to adopt the position of the entity to which the Great Other directs his message. Both discourses have the opportunity to abuse that position.
