In a world-exclusive interview in Doctor Who Magazine 586, Millie Gibson talks about playing new companion Ruby Sunday, what it’s like acting alongside Fifteenth Doctor Ncuti Gatwa, and how she discovered she’d secured the role:

“I went to get a spray tan for the NTAs [National Television Awards], and I was in the room waiting to dry off when I got this WhatsApp call, asking me to join the call with all my agents. I picked up the phone and they were like, ‘Are you good at keeping secrets?’ I said, ‘Yeah.’ They said, ‘Are you really good at keeping secrets? Cos you’ve got it.”
