It will be the third and final in its series and tonight's episode will take a look at The Doctor's many enemies.

Many new interviews with the programme's cast and crew feature on the documentaries and you can view a preview clip from tonight's episode below;

The first episode of this series aired on the twentieth of August and it took a look at both the ninth and tenth incarnations of The Doctor. Following on from the first episode, the second episode aired last week and that looked at The Doctor's many companions. Like with the first two episodes of the series, tonight's episode will air on BBC Three at 8pm and it will have an approximate running time of sixty minutes. The next episode of Doctor Who, The Waters of Mars, will air this November and more details will be posted as soon as they become available.
