Christopher Eccleston spoke to our Arts Correspondent, David Sillito.

He said that he hoped it would be programme that the family would watch together and that he was particularly aiming to capture the attention of 8 - 12 year olds.

He said that the sexism had been jettisoned and revealed that the cybermen are also not making a comeback. But he promised a new array of villains to add to those we already know.

Billie feels that the new Doctor Who is contemporary - both in terms of special effects, sets, storylines and the relationship between her character and the doctor.

Billie said their relationship has a very interesting dynamic and that sometimes he was a father figure to her character, who doesn't have a father.

She also feels that one of the biggest differences in the series is that its a lot more domestic: it touches on relationships and families in a way that previous series have not.
