Rhys Ifans and Laura Linney star in Parkinson's drama Onwards and Sideways

Rhys Ifans and Laura Linney play a couple who bond over their Parkinson's diagnoses in Onwards and Sideways, a Norfolk-set BBC film directed by John Madden. It is written by Vicar of Dibley co-creator Paul Mayhew-Archer, who has the disease. The actors describe it as devastating but laced with humour, and said they felt instantly safe working together.
