The series uses the British comic traditions of music hall and bawdy seaside postcards. Many titles parodied more serious films, such as their tongue-in-cheek homages to James Bond, westerns, and Hammer horror films. Carry On Emmannuelle, inspired by the soft-porn Emmanuelle, brought to an end the original Carry On run.
