Too Much of a Good Thing is a radio play, recorded entirely on location, as if it were a film, by Mike Leigh. Liane Aukin, the 'midwife' of the project, a BBC radio producer, knew Leigh through her brother David, the general manager at Hampstead Theatre. She had initially asked Leigh to revive Abigail's Party on the radio, but he preferred to supply an original piece. Ronald Mason, the head of radio drama, was enthusiastic and allocated £5000.
