A Slight Ache (1967)

In the breakfast room of a country house Flora and Edward are placidly finishing off breakfast, comfortably disputing as to whether the honeysuckle or convolvulus is in flower, and joining forces to drown a wasp in the marmalade jar. When a stranger appears at the garden gate his presence both disturbs and fascinates them.

Unfortunately the movie A Slight Ache is not yet available on HBO Max.
