World War Three (Doctor Who) World War Three (Doctor Who) "World War Three" is the fifth episode of the first series of the British science fiction television programme "Doctor Who" which was first broadcast on BBC One on 23 April 2005. It is the second of a two-part story which began with "Aliens of London" on 16 April. In the episode, set in London, the alien time traveller the Ninth Doctor (Christopher Eccleston) and his companion Rose Tyler (Billie Piper) team up with Rose's boyfriend Mickey Smith (Noel Clarke), her mother Jackie (Camille Coduri), and Member of Parliament Harriet Jones (Penelope Wilton) to foil the
Music of the Spheres (Doctor Who) admiring composer Giacomo Puccini; and the Ninth Doctor dancing with Rose Tyler to "In The Mood" by Glenn Miller in "The Doctor Dances". In writing the episode, Davies expressed hope that "this mini-adventure [would show] that music can take any shape or form, whether it’s singing, or playing the recorder, or even the spoons." He states that "music can go anywhere, reach anyone, and make better people of us all. Just like the Doctor." The mini-episode was filmed on Saturday 3 May 2008, the last day of filming for Series 4 of "Doctor Who", in the BBC Wales studios at
