One of the many unexpected talents required of the new companion was baking a soufflé (in last September’s Asylum of the Daleks). “It’s all in the whipping action,” giggles Jenna-Louise Coleman, who seems to have come to terms with the particular demands of the show. “I’d been doing period dramas for two years [Titanic, Dancing on the Edge] where you’re very still, so working with CGI, working with cameras when you’re constantly running, that’s a new experience.
“Mine and Matt’s dynamic is challenging,” she says. “Matt describes it as a dance, but to me it’s such a ping-pongy kind of dynamic.” The 26-year-old, who’s dating Game of Thrones star Richard Madden (Robb Stark), believes that Smith is a bigger diva than herself: “He demands sweets at certain times of the day and Diet Coke in his trailer.”
She’s confirmed she’ll be in next year’s Doctor Who, but of the latest episodes, The Rings of Akhaten (next week) is her favourite. “It’s Clara’s first experience of an alien world, realising what life will be like to travel with the Doctor. It’s big and heartfelt, but really funny. An epic episode wonderfully written by Neil Cross [Luther].” As for scary monsters, wait for the finale. “It’s a huge surprise, a monster with style.”
Doctor Who returns with The Bells of Saint John – Saturday at 6:15pm on BBC1
