Les Enfants terribles (French pronunciation: [lez‿ɑ̃fɑ̃ teʁibl]; literal English translation: The Terrible Children; English title: The Strange Ones)[2] is a 1950 French film directed by Jean-Pierre Melville, with a screenplay adapted by Jean Cocteau from his 1929 novel of the same name about the tangled relationship of a close brother and sister.

The film's soundtrack of Vivaldi concertos was unusual at the time and praised for its use in increasing the dramatic tension of the plot.

Elisabeth looks after her bedridden mother and is very protective of her teenage brother Paul, particularly after he is injured in a snowball fight and has to withdraw from school.

The siblings rarely leave their house, and, other than a doctor and maid, their only visitor is Paul's friend Gérard, who has a crush on Elisabeth.

Gérard often sleeps over, spending much of his time watching Elisabeth and Paul fight and play secret games in their shared bedroom.

When he dies in a car crash shortly after the wedding, Elisabeth inherits his fortune and mansion and brings Paul and Agathe to live with her.

The soundtrack consists of extracts from:[3] Cocteau had originally wanted the score to be jazz music, but was convinced by Melville to accept the use of the Vivaldi pieces instead.
