Before Nicola Walker and Stephen Mangan appeared on The One Show last year to promote the Christmas special of their BBC divorce drama The Split, they were warned not to go into too much detail about their next project: Mike Bartlett’s three-hander Unicorn, in which they play Polly and Nick, a married couple who bring a younger woman called Kate into their relationship.
Walker, joined by her co-stars in an empty London theatre bar, sets the scene: “We were told: ‘This is a tea-time show, so don’t say anything about the, um, sexual nature of the play.’” The three actors are seated today in a row behind a table, rather as if they are interviewing me for a job. Sandwiched between Walker and Mangan, suitably enough, is Erin Doherty, who starred as Princess Anne in The Crown and will complete the on-stage throuple.
