WHEN Jodie Whittaker watched TV shows as she was growing up, the people saving the day didn't look like her. They were "white guys, running around, doing really cool stuff", while the women on screen were so often on the sidelines, helping the heroic moment happen.
But now, aged 36, the Yorkshire-born actress is taking centre stage, the first woman to play The Doctor, in BBC One's long-running sci-fi series Doctor Who.
"It's 2018, women are not a genre, we are just the other half of the population, so to see us doing things shouldn't be such a surprise," sayss Whittaker when we meet at the studios in Cardiff, while she's on a break from filming.
"But I know it is, because I watch TV and film and we are often less active in things. Or we're the emotional point of view of a storyline, rather than the active one."
She continues: "There's lots of different actors in this show rather than different sexes – we're all just actors. And that's what we feel like this show represents.
"It's a moment and I'm a part of it and I'm proud of it. But I can't wait for it not to be a moment as well, so that someone going to drama school at 18 doesn't need to think, 'There aren't any jobs for me'."
The gender of the person controlling the Tardis isn't the only thing different about this series of Doctor Who, which returned to our screens in 2005 with Christopher Eccleston in the lead role (it had last aired in 1989 before that).
There's an all-new supporting cast, with Bradley Walsh, Mandip Gill and Tosin Cole playing The Doctor's companions. It's moving from Saturday to a Sunday evening slot, while new showrunner Chris Chibnall, of Broadchurch fame (which Whittaker also memorably starred in) – promises it's bigger and bolder than ever.
So how were Whittaker's nerves when she first arrived on set?
"It's always terrifying to do your first ever take," says the energetic actress, whose TV credits also include the lead in BBC hit Trust Me, costume drama Tess Of The D'Urbervilles and an episode of Netflix's Black Mirror.
"My first ever take on Broadchurch was a tracking wide, that ended up in tracking close-ups of being told, in our sitting room, that Danny Latimer had been killed.
"That is an amazing learning experience for any actor to be put through, to be thrown in. When it's something as harrowing as that, you can't pre-empt it, so it happens and has to take you by surprise as much as it can do as an actor, because it isn't real."
With Doctor Who, Whittaker adds, the sense of responsibility she feels to be honest and truthful was "weighted with 55 years of history".
"So there's the natural nerves you have of doing any job you're passionate about... Cut to the responsibility of those shoes to fill and I'd be absolutely lying if I said I didn't feel it," she says. "But once you've done your first set-up of the first scene and you move on from the first set-up and it's tattooed on film forever, you are like, 'It's not that bad'."
Whittaker, who is married to American actor Christian Contreras, is chatting while still in costume – a blue striped top over long white sleeves, turquoise trousers and brown braces. It's a look, she says, in which she had loads of input – in fact, between auditions, she was already sending Chibnall photos of inspiration.
One image she found showed a "woman, walking with purpose" wearing boots, short trousers, braces and a T-shirt, and with unkempt hair.
"It didn't lend itself to a man's outfit, or a woman's outfit, it was a feeling, and that's what I wanted to help create – more of a feeling than a costume," she says.
However, once she bagged the role of the 13th incarnation of The Doctor, she was careful not to make too many decisions about how she would play it.
"No point me thinking, 'I'm going to be this kind of Doctor' too much before I started shooting, because I had no idea what it was like to work with these guys, no idea what it was like to have any of the energy of the guest stars," she says.
"It was best to be open, and I think that plays into the Doctor I wanted to play, that open-heartedness and chaos within an ability to find a stillness in the tiniest details."
It's clear from Whittaker's fast-paced responses, and visible nervousness as she bites her nails while her co-stars talk, that she's hugely excited by the turn her career has taken.
Specific details about what we can expect from this series have been kept very hush-hush. But while Whittaker is determined not to give any spoilers away, she does let on what themes she thinks are important this series.
"Friendship and loyalty and survival," she says. "All things that are very human, interlaced with things that are very far from human and familiar. It's a very inclusive world."
:: Doctor Who returns to BBC One on Sunday October 7.
