The Meaning of Martha

Freema explains all to Radio Times.

"Martha is very different from Rose," explains Freema Agyeman in a special 16-page new series guide in the new edition of Radio Times.

"She's academic and very independent. She has her own flat and she's almost qualified to be a doctor, whereas Rose was living at home with her mum, and there was that feeling of slight disgruntlement with her life. She was searching for something when the Doctor came along and helped her find herself.

"With Martha, it's more a sense of interruption," she adds. "She seems very grounded and happy with where she's at, then the Doctor comes along and kind of blows everything out of the water for her. She goes with him more out of curiosity than need.

"She comes from this bustling family, and when we first see her, they're all turning to her for advice. Even though she's not the eldest, she seems to be the boss. Martha has an old head on young shoulders and that's what makes her more challenging of the Doctor. She wants answers.

"We're all slightly different around different people, so Martha brings out different facets of the Doctor that maybe the audience hasn't seen before. There's a freshness and an openness and a directness to Martha. Shes quite tough."

The special also coverage also includes interviews with David Tennant, exclusive information on the new monsters plus a complete episode guide by Russell T Davies. It's also got two collectors edition covers - hurrah!
