An Inspector Calls is a 1954 British drama film directed by Guy Hamilton and starring Alastair Sim, Jane Wenham and Eileen Moore.

It is based upon the 1945 play An Inspector Calls by J.B. Priestley and was adapted for the screen by Desmond Davis.

It was shot at Shepperton Studios with sets designed by the art director Joseph Bato.

In 1912, the upper class Birling family sit at a dining table at the end of a dinner party with their friends.

They are interrupted by a man calling himself Inspector Poole, investigating the suicide of a working-class girl, Eva Smith, whose death is linked to each family member.

The inspector explains that after a period of unemployment she went to work at Lilworth's but was dismissed after two months after a customer complained.

Sheila accuses Eva of being rude for smiling as she struggles to fit the hat and demands she is dismissed.

Gerald phones the infirmary to check the girl is really dead but is told no-one died.

Mr and Mrs Birling decide to go back to how they were, though Sheila and Eric are permanently changed.

In the play, the Inspector is ushered in by the maid, while in the film he simply appears suddenly in the dining room as if from nowhere, accompanied by an ominous chord in the background music.

In the middle of the film, he inspects his pocket watch and asks Eric to enter the room.
