The actor on her Dua Lipa faux pas, restless legs syndrome, and a shock realisation at a housewarming party

Born in Bristol, Tuppence Middleton, 39, trained at ArtsEd in London before appearing in films The Imitation Game and Mank. Her stage roles include The Motive and the Cue at the National Theatre, and her TV work spans Sense8, War and Peace, The Forsytes and the next series of Slow Horses. Since the age of 11, she has had obsessive-compulsive disorder (OCD), which she writes about in Scorpions, out in paperback on 21 May. She lives in London with Swedish film director Måns Mårlind and their child.

What is your greatest fear?
Endless vomiting. That comes from my emetophobia, which is a huge part of my OCD.
