The CRM 114 Discriminator is a fictional piece of radio equipment in Stanley Kubrick's film Dr. Strangelove (1964), the destruction of which prevents the crew of a B-52 from receiving the recall code that would stop them from dropping their hydrogen bomb payloads onto Soviet territory.
The device is one of several that malfunction in the film, along with Mandrake's telephones, the bomb doors failing to open and the Doomsday Weapon's misuse, a common theme in Kubrick's work of the failure of human planning.
