The film, starring Rhys Ifans and Laura Linney, is a touching story about two people who have lots in common – including Parkinson’s.
Ifans plays the role of Tony Evans, the deputy head of a local primary school, while Linney portrays Emma Dretzin, a pianist, composer and single mother of two daughters.

The characters do not know each other until an encounter changes the course of their lives when, on the same morning, they are both diagnosed with Parkinson’s.
Filming took place in parts of north Norfolk last year, including Fakenham, and is also set in the area.
Monica Dolan, from Mr Bates vs The Post Office and Black Mirror, and Rory Kinnear, who is in The Diplomat on Netflix, also star in the 90-minute film.
