Idea of Doctor Who

Doctor Who is a science fiction programme and it's all about travelling in time and space and saveing the Earth or the Universe from different kind of threats.

The Doctor's species is a Time Lord and he is last of his kind. He is over 900 years old, he has two hearts and he always travels with a companion. The companion is usually a human.

When the Doctor dies, he can regenerate himself. Then he gets a new body and a new face. That is the way how the whole programme can continue naturally and the leading actor can be changed easilly. Usually the same actor plays the Doctor about three seasons.

A Time Lord can regenerate him/herself to a woman or to a man. In fact for the first time the Doctor will be a woman in 11th season.

The Doctor's name is a secret and that is why the name of the show is Doctor Who. No one knows his name exept  Doctor and his wife River Song.

Tardis is the Doctor's timemachine. The name Tardis comes from the words Time And Relative Dimensions In Space. The Tardis looks like an old British police box and it's bigger on the inside than the outside.
