The film Mine Own Executioner, released in England in 1947, is worth our attention because of the authenticity of its depiction of analytic psychotherapy, the dramatic and visual manner with which it explores the possibilities and limitations of the treatment itself, and the convincing portrayal of the psychotherapist's conflicts and struggles in response to the treatment. The film is also notable for its dramatic exploration of such issues as lay analysis, war neuroses, the schizoid personality, and schizophrenia. Finally, the film offers us the opportunity to explore the relationship between narrativity in film and psychotherapy with some help from Freud's concept of Nachträglichkeit.
