Priestley's "An Inspector Calls" is a gripping and thought-provoking mystery that masterfully weaves together the intricacies of a whodunit with the social commentary of a period drama. Directed by Guy Hamilton, the movie takes place in the early 20th century and revolves around the Birling family, whose dinner party is disrupted by the arrival of a mysterious inspector investigating the death of a young woman. As the story unfolds, the inspector's questioning reveals a complex web of relationships and secrets that expose the family's hypocrisy and social responsibility.
