A Spot of Bother (French: Une petite zone de turbulences) (A small area of turbulence), is a French comedy drama film directed by Alfred Lot and starring Michel Blanc, released in 2010, and based on the 2006 novel by the English writer Mark Haddon A Spot of Bother.

One day, in a changing-room while buying a new suit, Jean-Paul finds a spot on his hip, and although reassured by his doctor that it is just discoid eczema, he panics and believes he has skin cancer.

Claiming to need a change of air, Jean-Paul decides to visit his brother (whom he can't stand) but abandons his trip and returns home, and, without being noticed, catches Anne and David having sex in the marital bed, and from then on behaves more and more strangely.

Eventually Cathie and Philippe reconcile and the marriage plans go ahead, but on the day Jean-Paul takes the wrong doses of his medicines, and tries to avoid the ceremony.

[1] It deals with events in the life of a 57-year-old early retired man who finds a lesion on his hip, and despite reassurance from his doctor, transforms the spot into a malignant skin cancer, and what happens as he tries remain sane; "the novel moves in and out of the lives and minds of George’s wife, son, and daughter".

[4] The book's plot outline and character relations are retained in the film, but the action is moved from Peterborough and London in England to Paris and the surrounding Île-de-France region.

George and Jean Hall become Jean-Paul and Anne Muret, Katie and Ray become Cathie and Philippe, and Jamie and Tony become Mathieu and Olivier.
