An Inspector Calls is a 2015 British thriller television film written by Helen Edmundson, based on the 1945 J. B. Priestley play of the same name. It is directed by Aisling Walsh, produced by Howard Ella and stars David Thewlis as the titular character. The film was first broadcast on 13 September 2015 on BBC One.

The film is set in 1912 and follows the events of a single evening on which the wealthy Birling family is holding a dinner party to celebrate the engagement of their daughter. The festivities are interrupted by a visit from what is taken to be a policeman, Inspector Goole, who is investigating the recent suicide of a local young woman. Goole’s interrogations of each member of the dinner party make it clear that all of them have contributed to the tragedy through individually unjust, selfish or exploitative behaviour. The "Inspector" leaves the subdued group with a warning that human beings have shared responsibility for each other and that this lesson will soon be taught "in fire and blood and anguish" — an apparent reference to the outbreak of World War I two years later.

Final scenes establish that Goole is not a real policeman, and suggest that he is some form of supernatural messenger.
